## What's the Easiest Way to Convert Fahrenheit to Celsius?

What's the difference between Celsius and Fahrenheit? It's really a quirk of history and a simple mathematical conversion. Learn the easiest way to convert Fahrenheit to Celsius as well as the reverse calculation with simple equations and a chart. thermometer in snow Celsius and Fahrenheit

### Converting Fahrenheit to Celsius

Some would consider a quick estimate the easiest way to convert a Fahrenheit temperature to a Celsius temperature. Others want a more precise answer quickly. Here, you can learn both methods.

### Fahrenheit to Celsius Estimate Formula

Use this formula to get a good estimate of the Celsius temperature when converting from Fahrenheit. In this case / means divided by or to use division.

(Fahrenheit temp. [F]-30)/2 = Celsius temp.

In other words, if you’d like to convert a Fahrenheit temperature to an approximate Celsius temperature:

2. Subtract 30 from this figure (e.g., 100 - 30 = 70).
3. Divide your answer by 2 (e.g., 70 / 2 = 35).

### Fahrenheit to Celsius Exact Formula

If you want a more precise calculation, you can use the more exact formula. Using this calculation, we determine that 100 degrees Fahrenheit is equivalent to 37.78 degrees Celsius.

(F - 32) / 1.8 = C

In other words, if you'd like to convert a temperature reading in Fahrenheit to Celsius:

2. Subtract 32 from this figure (e.g., 100 - 32 = 68).
3. Divide your answer by 1.8 (e.g., 68 / 1.8 = 37.78)

### Converting Celsius to Fahrenheit

To convert Celsius to Fahrenheit, simply reverse the equation. In this case * means times, or to use multiplication.

(C * 1.8) + 32 = F

You can use this equation to show that 100 degrees Celsius is equal to 212 degrees Fahrenheit.

2. Multiply this figure by 1.8 (e.g., 100 * 1.8 = 180).
3. Add 32 to this figure (e.g., 180 + 32 = 212).

### Fahrenheit to Celsius Conversion Chart

If you really want an easy way to convert temperatures, you can use this Fahrenheit to Celsius conversion chart where the math has already been done for you.

### What's the Difference Between Fahrenheit and Celsius?

If you're from the United States, you're probably accustomed to describing temperature by Fahrenheit. A very hot summer day is 100 degrees, a pleasant spring morning is 50 degrees, and 0 degrees is ungodly cold. If you're from almost anywhere else, you likely favor Celsius, where 0 degrees is only pretty cold, 50 degrees is unspeakably hot, and 100 degrees happens on a stove, not outside.

### Are Fahrenheit and Celsius Readings Ever the Same?

If you were wondering if there is a temperature where Fahrenheit and Celsius are the same, it's at 40 below zero, also known as -40 or negative 40. At all other temperatures, the difference is history.

### History of Fahrenheit and Celsius Scales

Globally, the standard scale for everyday use is Celsius. Only the United States, islands freely associated with the US (Palau, the Marshall Islands and Micronesia), the Bahamas, the Caymans, and Liberia use Fahrenheit as their primary temperature measurement. Everybody else goes with Celsius.

### History of the Fahrenheit Scale

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit in 1724. Fahrenheit invented his scale for use with mercury thermometers, which he also invented. The Fahrenheit scale is a bit older than the Celsius scale.

### History of the Celsius Scale

The Celsius scale was created by Anders Celsius in 1745, a couple decades after Fahrenheit. Curiously, Celsius created the reverse of the modern scale, treating 0 as the boiling point of water and 100 as the freezing point of water. Other scientists, notably Carl Linnaeus, flipped it later that year, making 0 the freezing point and 100 the boiling point of water.

Since it was originally built as a scale between 0 and 100, Celsius is also called centigrade. The word "centigrade" literally describes something that consists of or is divided into 100 degrees. That said, Celsius has been the preferred nomenclature since 1948.

### The Kelvin Temperature Unit

You may have heard of temperature being measured according to kelvin. Indeed, if you're involved in the sciences, you probably use kelvin. Kelvin is a bit different than Fahrenheit and Celsius. Celsius and Fahrenheit are both temperature scales, measuring temperatures in degrees.

### History of the Kelvin Unit

Named after Lord Kelvin, a kelvin is a standard scientific unit, like a kilogram for weight or a meter for distance. The proper way to use the word, then, is not "100 degrees Kelvin" but "100 kelvin." (Note the lower case "k" in kelvin.)

1 kelvin equals 1/273.16th of the triple point of water: that is, the point at which liquid water, water vapor and solid ice can coexist. In other words, 273.16 kelvin is the exact triple point of water.

### The Importance of Kelvin

The importance of kelvin is that it measures absolute temperature: absolute zero is 0 kelvin, the temperature at which all atomic motion (which creates heat) stops. There is no thermal energy whatsoever at absolute zero.

### Kelvin Conversion Formulas

Kelvin is primarily of value to scientists, since it simplifies calculation at extreme temperatures. For your convenience, the conversion equations follow.

• To convert: Celsius to kelvin: C + 273.15 = K.
• To convert Fahrenheit to kelvin: [(F - 32) / 1.8] + 273.15 = K

You convert Celsius to Kelvin by simply adding 273.15. If the outside temperature is 10 degrees Celsius, then it is 283.15 kelvin. That's easy enough.

Fahrenheit is a bit trickier. Take your degrees Fahrenheit, subtract 32, divide by 1.8, and finally add 273.15. Here's a quick example:

1. Say it is 100 degrees Fahrenheit outside.
2. Subtract 32 from 100 to get 68.
3. Divide 68 by 1.8 to get 37.78.
4. Add 273.15 to get 310.93. Thus, 100 degrees Fahrenheit is equal to 310.93 kelvin.

### Taking Temperatures

Temperature is important! Measuring heat accurately matters in every field of human endeavor, from engineering to medicine. For more on how to manage your temperature, take a look at this automatic Celsius to Fahrenheit converter. It'll make short work of all your temperature conversions.

## Conversion of Temperature

### Quick Celsius (°C) / Fahrenheit (°F) Conversion:

measure/images/thermometer.js?mode=boxes

Type a value in either box

Or use the slider

Or the Interactive Thermometer

Or this method:

 °C to °F Divide by 5, then multiply by 9, then add 32 °F to °C Deduct 32, then multiply by 5, then divide by 9

(Explanation Below ...)

### Typical Temperatures

(only bold are exactly the same)

°C °F Description 220 430 Hot Oven 180 360 Moderate Oven 100 212 Water boils 40 104 Hot Bath 37 98.6 Body temperature 30 86 Beach weather 21 70 Room temperature 10 50 Cool Day 0 32 Freezing point of water −18 0 Very Cold Day −40 −40 Extremely Cold Day (and the same number!)

### Explanation

There are two main temperature scales:

• °C, the Celsius Scale (part of the Metric System, used in most countries)
• °F, the Fahrenheit Scale (used in the US)

They both measure the same thing (temperature!), but use different numbers:

• Boiling water (at normal pressure) measures 100° in Celsius, but 212° in Fahrenheit
• And as water freezes it measures 0° in Celsius, but 32° in Fahrenheit

Like this: Looking at the diagram, notice:

• The scales start at a different number (0 vs 32), so we will need to add or subtract 32
• The scales rise at a different rate (100 vs 180), so we will also need to multiply

And so, to convert:

from Celsius to Fahrenheit: first multiply by 180100, then add 32

from Fahrenheit to Celsius: first subtract 32, then multiply by 100180

180100 can be simplified to 95,
and 100180 can be simplified to 59, so we get this:

°C to °F:   Divide by 5, then multiply by 9, then add 32

°F to °C:   Subtract 32, then multiply by 5, then divide by 9

### Example: Convert 25° Celsius (a nice warm day) to Fahrenheit

First: 25° / 5 = 5
Then: 5 × 9 = 45
Then: 45 + 32 = 77° F

### Example: Convert 98.6° Fahrenheit (normal body temperature) to Celsius

First: 98.6° − 32 = 66.6
Then: 66.6 × 5 = 333
Then: 333 / 9 = 37° C

We can swap the order of divide and multiply if we want, but don't change the add or subtract. So this is also OK:

### Example: Convert 98.6° Fahrenheit to Celsius (again)

First: 98.6° − 32 = 66.6
Then: 66.6 / 9 = 7.4
Then: 7.4 × 5 = 37° C

(Same answer as before, was it easier or harder this way?)

We can write them as formulas:

Celsius to Fahrenheit:   (°C × 95) + 32 = °F
Fahrenheit to Celsius:   (°F − 32) × 59 = °C

### Use 1.8 instead of 9/5

9/5 is equal to 1.8, so we can also use this method:

Celsius to Fahrenheit:   °C × 1.8 + 32 = °F
Fahrenheit to Celsius:   (°F − 32) / 1.8 = °C

To make "×1.8" easier we can multiply by 2 and subtract 10%, but it only works for °C to °F:

Celsius to Fahrenheit:   (°C × 2) less 10% + 32 = °F

### Example: Convert 20° Celsius (A nice day) to Fahrenheit

• 20x2 = 40
• less 10% is 40−4 = 36
• 36+32 = 68° F

### Add 40, Multiply, Subtract 40

Since both scales cross at −40° (−40° C equals −40° F) we can:

• multiply by 5/9 (for °F to °C), or 9/5 (for °C to °F)
• subtract 40

Like this:

Celsius to Fahrenheit:   Add 40, multiply by 9/5, then subtract 40
Fahrenheit to Celsius:   Add 40, multiply by 5/9, then subtract 40

### Example: Convert 10° Celsius (A cool day) to Fahrenheit

• 10+40 = 50
• 50×9/5 = 90
• 90−40 = 50° F

To remember 9/5 for °C to °F think "F is greater than C, so there are more °F than °C"

### Quick, but Not Accurate

Celsius to Fahrenheit:   Double, then add 30
Fahrenheit to Celsius:   Subtract 30, then halve

Examples °C → °F:

• 0° C → 0+30 → 30° F (low by 2°)
• 10° C → 20+30 → 50° F (exact!)
• 30° C → 60+30 → 90° F (high by 4°)
• 180° C → 360+30 → 390° F (high by 34°, not good)

Examples °F → °C:

• 40° F → 10/2 → 5° C (almost right)
• 80° F → 50/2 → 25° C (low by about 2°)
• 120° F → 90/2 → 45° C (low by about 4°)
• 450° F → 420/2 → 210° C (low by about 22°, not good) Footnote: Temperature is a measure of how fast an object's particles are moving.

## How do you convert Celsius to Fahrenheit and what are the hottest temperatures recorded in the UK?

THERE are two ways to measure temperature, Celsius and Fahrenheit.

The one officially used and recognised in the UK is Celsius but many other places around the world use the Fahrenheit scale. Here's how you can figure out the temp no matter the format.

### Why is there degrees Celsius and Fahrenheit?

Degrees Celsius is the most common format of temperature in the UK.

It comes from the metric system of measurement, whereas Fahrenheit is taken from the Imperial system.

The UK began the switch to the Metric system from the Imperial system in the 60s.

The Metric system started being taught in schools in 1974, meaning that most people are more familiar with Celsius than Fahrenheit.

### How do you convert Celsius to Fahrenheit?

If the temperature is 0 degrees Celsius then it will be 32 degrees Fahrenheit.

In order to convert a temperature from Celsius to Fahrenheit, multiply the °C temperature by 1.8 and add 32 to the number.

This is the answer in °F.

### How do you convert Fahrenheit to Celsius?

In order to convert degrees Fahrenheit into Celsius, first, take the °F temperature and subtract 32.

Multiply the number you are left with by five, then divide the number by nine.

This is the answer in °C.

### What was the hottest temperature ever recorded in the UK?

The hottest temperature in the UK was recorded in Gravesend, Kent on Sunday, August 10, 2003.

The temperature hit 38°C (100.6°F), topping the last record taken earlier that same day in Heathrow, where the temperature soared to 37.9°C (100.2°F).

Before that record-breaking day, the hottest temperature ever recorded in UK history was in Cheltenham in 1990; the mercury hit 37.1°C (98.8°F).

A more recent record came on June 21, 2017, when Britain had it's hottest June day for 40 years.

The temperature was recorded at Heathrow, where the thermometer hit a scorching 34.5°C (94.1°F).

That Wednesday came close to the highest June temp ever recorded - 35.6°C (96.08°F) recorded in Southampton in June 1976.

• And as water freezes it measures 0° in Celsius, but 32° in Fahrenheit

Like this: Looking at the diagram, notice:

• The scales start at a different number (0 vs 32), so we will need to add or subtract 32
• The scales rise at a different rate (100 vs 180), so we will also need to multiply

And so, to convert:

from Celsius to Fahrenheit: first multiply by 180100, then add 32

from Fahrenheit to Celsius: first subtract 32, then multiply by 100180

180100 can be simplified to 95,
and 100180 can be simplified to 59, so we get this:

°C to °F:   Divide by 5, then multiply by 9, then add 32

°F to °C:   Subtract 32, then multiply by 5, then divide by 9

### Example: Convert 25° Celsius (a nice warm day) to Fahrenheit

First: 25° / 5 = 5
Then: 5 × 9 = 45
Then: 45 + 32 = 77° F

### Example: Convert 98.6° Fahrenheit (normal body temperature) to Celsius

First: 98.6° − 32 = 66.6
Then: 66.6 × 5 = 333
Then: 333 / 9 = 37° C

We can swap the order of divide and multiply if we want, but don't change the add or subtract. So this is also OK:

### Example: Convert 98.6° Fahrenheit to Celsius (again)

First: 98.6° − 32 = 66.6
Then: 66.6 / 9 = 7.4
Then: 7.4 × 5 = 37° C

(Same answer as before, was it easier or harder this way?)

We can write them as formulas:

Celsius to Fahrenheit:   (°C × 95) + 32 = °F
Fahrenheit to Celsius:   (°F − 32) × 59 = °C

### Use 1.8 instead of 9/5

9/5 is equal to 1.8, so we can also use this method:

Celsius to Fahrenheit:   °C × 1.8 + 32 = °F
Fahrenheit to Celsius:   (°F − 32) / 1.8 = °C

To make "×1.8" easier we can multiply by 2 and subtract 10%, but it only works for °C to °F:

Celsius to Fahrenheit:   (°C × 2) less 10% + 32 = °F

### Example: Convert 20° Celsius (A nice day) to Fahrenheit

• 20x2 = 40
• less 10% is 40−4 = 36
• 36+32 = 68° F

### Add 40, Multiply, Subtract 40

Since both scales cross at −40° (−40° C equals −40° F) we can:

• multiply by 5/9 (for °F to °C), or 9/5 (for °C to °F)
• subtract 40

Like this:

Celsius to Fahrenheit:   Add 40, multiply by 9/5, then subtract 40
Fahrenheit to Celsius:   Add 40, multiply by 5/9, then subtract 40

### Example: The reach key west spa 10° Celsius (A cool day) to Fahrenheit

• 10+40 = 50
• 50×9/5 = 90
• 90−40 = 50° F

To remember 9/5 for °C to °F think "F is greater than C, so there are more °F than °C"

### Quick, but Not Accurate

Celsius to Fahrenheit:   Double, then add 30
Fahrenheit to Celsius:   Subtract 30, then halve

Examples °C → °F:

• 0° C → 0+30 → 30° F (low by 2°)
• 10° C → 20+30 → 50° F (exact!)
• 30° C → 60+30 → 90° F (high by 4°)
• 180° C → 360+30 → 390° F (high by 34°, not good)

Examples °F → °C:

• 40° F → 10/2 → 5° C (almost right)
• 80° F → 50/2 → 25° C (low by about 2°)
• 120° F → 90/2 → 45° C (low by about 4°)
• 450° F → 420/2 → 210° C (low by about convert 45 f to c, not good) Footnote: Temperature is a measure of how fast an object's particles are moving.

## How do you convert Celsius to Fahrenheit and what are the hottest temperatures recorded in the UK?

THERE are two ways to measure temperature, Celsius and Fahrenheit.

The one officially used and recognised in the UK is Celsius but many other places around the world use the Fahrenheit scale. Here's how you can figure out the temp no matter the format.

### Why is there degrees Celsius and Fahrenheit?

Degrees Celsius is the most common format of temperature in the UK.

It comes from the metric system of measurement, whereas Fahrenheit is taken from the Imperial system.

The UK began the switch to the Metric system from the Imperial system in the 60s.

The Metric system started being taught in schools in 1974, convert 45 f to c that most people are more familiar with Celsius than Fahrenheit.

### How do you convert Celsius to Fahrenheit?

If the temperature is 0 degrees Celsius then it will be 32 degrees Fahrenheit.

In order to convert a temperature from Celsius to Fahrenheit, multiply the °C temperature by 1.8 and add 32 to the number.

This is the answer in °F.

### How do you convert Fahrenheit to Celsius?

In order to convert degrees Fahrenheit into Celsius, first, take the °F temperature and subtract 32.

Multiply the number you are left with by five, then divide the number by nine.

This is the answer in °C.

### What was the hottest temperature ever recorded in the UK?

The hottest temperature in the UK was recorded in Gravesend, Kent on Sunday, August 10, 2003.

The temperature hit 38°C (100.6°F), topping the last record taken earlier that same day in Heathrow, where the temperature soared to 37.9°C (100.2°F).

Before that record-breaking day, the hottest temperature ever recorded in UK history was in Cheltenham in 1990; the mercury hit 37.1°C (98.8°F).

A more recent record came on June 21, 2017, when Britain had it's hottest June day for 40 years.

The temperature was recorded at Heathrow, where the thermometer hit a scorching 34.5°C (94.1°F).

That Wednesday came close to the highest June temp ever recorded - 35.6°C (96.08°F) recorded in Southampton in June 1976.

## How to Convert Fahrenheit to Celsius

Fahrenheit and Celsius are the scales most often used for reporting room, weather, and water temperatures. The Fahrenheit scale is used in the United States, while the Celsius scale is used worldwide.

Indeed, most countries around the world measure their weather and temperatures using the relatively simple Celsius scale. But the United States is one of just a few remaining countries that use Fahrenheit, so it's important for Americans to know how to convert one to the other, especially old homes for sale in san antonio traveling or doing scientific research.

### How to Convert Convert 45 f to c

First, you need the formula for converting Fahrenheit (F) to Celsius (C):

The i want to pay my metro phone bill online C represents the temperature in Celsius, and F is the temperature in Fahrenheit. After you know the formula, it is easy to convert Fahrenheit to Celsius with these three steps.

1. Subtract 32 from the Fahrenheit temperature.
2. Multiply this number by five.
3. Divide the result by nine.

For example, suppose the temperature is 80 degrees Fahrenheit and you want to know what the figure would be in Celsius. Use the above three steps:

1. 80 F – 32 = 48
2. 5 x 48 = 240
3. 240 / 9 = 26.7 C

So the temperature in Celsius is 26.7 C.

### Fahrenheit to Celsius Example

If you want to convert a normal human body temperature (98.6 F) to Celsius, plug the Fahrenheit temperature into the formula:

As noted, your starting temperature is 98.6 F. So you would have:

• C = 5/9 x (F - 32)
• C = 5/9 x (98.6 - 32)
• C = 5/9 x (66.6)
• C = 37 C

Check your answer to ensure it makes sense. At ordinary temperatures, a Celsius value is always lower than the corresponding Fahrenheit value. Also, it's helpful to keep in mind that the Celsius scale is based on the freezing and boiling points of water, where 0 C is the freezing point and 100 C is the boiling point. On the Fahrenheit scale, water freezes at 32 F and boils at 212 F.

### Conversion Shortcut

You often don't need an exact conversion. If you're traveling to Europe, for example, and you know the temperature is 74 F, you might want to know the approximate temperature in Celsius. The website Lifehacker offers this tip on making an approximate conversion:

Fahrenheit to Celsius: Subtract 30 from the Fahrenheit temperature and then divide by two. So, using the approximation formula:

• 74 F – 30 = 44
• 44 / 2 = 22 C

(If you go through the previous formula's calculations for the exact temperature, you arrive at 23.3.)

Celsius to Fahrenheit: To reverse the approximation and convert from 22 C to Fahrenheit, multiply by two and add 30. So:

• 22 C x 2 = 44
• 44 + 30 = 74 C

### Quick Conversion Table

You can save even more time by using predetermined conversions. The Old Farmer's Almanac offers this table for making quick conversions from Fahrenheit to Celsius.

Note how the Fahrenheit and Celsius scales read the same temperature at -40.

### Invention of Fahrenheit

While you're mastering these conversions, it might be interesting to learn how the Fahrenheit temperature scale came into existence. The first mercury thermometer was invented by German scientist Daniel Fahrenheit in 1714. His scale divides the freezing and boiling points of water into 180 degrees, with 32 degrees as water's freezing point, and 212 as its boiling point.

On Fahrenheit's scale, zero degrees was determined as the temperature of a temperature-stable brine solution of ice, water, and ammonium chloride. He based the scale on the average temperature of the human body, which he originally calculated at 100 degrees. (As noted, it's since been adjusted to 98.6 degrees Fahrenheit.)

Fahrenheit was the standard unit of measure in most countries until the 1960s and 1970s when it was replaced with the Celsius scale in a widespread conversion to the more useful metric system. In addition to the United States and its territories, Fahrenheit is still used in the Bahamas, Belize, and the Cayman Islands for most temperature measurements.

### Definition of temperature:

The tendency of a substance or an object to transfer heat to its surroundings.

Definition of the thermodynamic temperature:

The Kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water (13de CGPM (1967), Rés. 4)
Reference: http://physics.nist.gov/cuu/Units/current.html

In the 13th CGPM in 1967 was decided that the unit of temperature will be the Kelvin, and not 'degrees Kelvin'. The triple point of water is 273.16 K, which is 0.01 oC (degrees Celsius).

### Definition of Celsius:

The Celsius-scale is defined by the follow two points:

1. The triple point of water is defined as 0.01 oC.
2. One degree Celsius equals the change of temperature with one degree on the ideal gas-scale.

The triple point is a theoretical point where the three phases of a matter (for example water) come together. This means that liquid, solid and gas phase from a matter appear at the same time. This is practically impossible.

### History of measuring temperature:

The idea of measuring temperature exists a long time. One of the first who wanted to make a temperature scale was Galen (ca. 170). He had a scale of convert 45 f to c degrees warmth and 4 degrees of cold. The earlier measurement instruments for temperature where called thermo scopes. In 1610 Galileo introduced wine in the thermo scopes instead of air. In 1724 Gabriel Fahrenheit introduced the medium mercury in the thermo scopes. The reason that mercury was used is that the thermal expansion of mercury is large, mostly homogeneous and it does not stick on the glass. Mercury also stays in the liquid phase for a great range of temperature. It is also easy to read.

### Present temperature scales:

Present temperature scales have two basic points: from when the water starts to freeze and when it starts to boil. Between these two temperatures a scale is made. The two most popular scales are the Celsius (made by Anders Celsius) and Fahrenheit (made by Gabriel Fahrenheit) scale. The Fahrenheit scale is defined so that the melting point of water lays by 32 degrees Fahrenheit and the boiling point lays by 212 degrees Fahrenheit. This means that between the freezing point and boiling point there are 180 divisions. Fahrenheit introduced his scale in 1724.

Another scale is the Celsius scale. In the Celsius scale the freezing point of water is set at 0 degrees (centigrade) and the convert 45 f to c point at 100 degrees (centigrade). This scale exists on 100 divisions, also known as centiscale. In 1948 the centidegrees (centigrade scale) were replaced by the degrees Celsius (oC). The Celsius scale is defined by the following two points:

1. The triple point of water is defined at 0.01 oC.
2. One degree Celsius equals the change of temperature with one degree on the ideal gas-scale.

On the Celsius-scale the boiling point of water with a pressure of 1 atmosphere is set at 99.975 oC. With the centiscale it was 100.

### SI temperature scale:

Temperature is related with the kinetic energy of the molecules. The kinetic energy changes when the temperature changes. Temperature is defined as the translation of heath between two objects. The fundamental temperature scale is the one of Kelvin. The temperature scale of Kelvin depends of the absolute zero point. This is the point where the molecules do not move anymore, so they do not give warmth. This is for all molecules. The absolute zero point is by 0 K, this is -273.15 oC. The scale is the same as the Celsius.

If you wish you can reverse the conversion convert 45 f to c using the converter for fahrenheit to celsius

For other conversions in temperature, use the temperature conversion tool.

Celsius is, or relates to, the Celsius temperature scale (previously known as the centigrade scale). The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as serve as unit increment to indicate a temperature interval (a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701 – 1744), who developed a similar temperature scale two years before his death. See all conversions for Celsius here.

Fahrenheit is a temperature scale named after the Polish–German physicist Daniel Gabriel Fahrenheit (1686–1736), who proposed it in 1724. In this scale, the freezing point of water is 32 degrees Fahrenheit convert 45 f to c "32 °F"), and the boiling point is 212 degrees, placing the boiling and freezing points of water exactly 180 degrees apart. On the Convert 45 f to c scale, the freezing and boiling points of water are exactly 100 degrees apart, thus the unit of this scale, a degree Fahrenheit, is 5⁄9 of a degree Celsius. Negative 40 degrees Fahrenheit (-40 °F) is equal to negative 40 degrees Celsius (-40 °C). See all conversions for Fahrenheit here.

## How to Convert Fahrenheit to Celsius

Fahrenheit and Celsius are the scales most often used for reporting room, weather, and water temperatures. The Fahrenheit scale is used in the United States, while the Celsius scale is used worldwide.

Indeed, most countries around the world measure their weather and temperatures using the relatively simple Celsius scale. But the United States is one of just a few remaining countries that use Fahrenheit, so it's important for Americans to know how to convert one to the other, especially when traveling or doing scientific research.

### How to Convert Temperatures

First, you need the formula for converting Fahrenheit (F) to Celsius (C):

The notation C represents the temperature in Celsius, and F is the temperature in Fahrenheit. After you know the formula, it is easy to convert Fahrenheit to Celsius with these three steps.

1. Subtract 32 from the Fahrenheit temperature.
2. Multiply this number by five.
3. Divide the result by nine.

For example, suppose the temperature is 80 degrees Fahrenheit and you want to know what the figure would be in Celsius. Use the above three steps:

1. 80 F – 32 = 48
2. 5 x 48 = 240
3. 240 / 9 = 26.7 C

So the temperature in Celsius is 26.7 C.

### Fahrenheit to Celsius Example

If you want to convert a normal human body temperature (98.6 F) to Celsius, plug the Fahrenheit temperature into the formula:

As noted, your starting temperature is 98.6 F. So you would have:

• C = 5/9 x (F - 32)
• C = 5/9 x (98.6 - 32)
• C = 5/9 x (66.6)
• C = 37 C

Check your answer to ensure it makes sense. At ordinary temperatures, a Celsius value is always lower than the corresponding Fahrenheit value. Also, it's helpful to keep in mind that the Celsius scale is based on the freezing and boiling points of water, where 0 C is the freezing point and 100 C is the boiling point. On the Fahrenheit scale, water freezes at 32 F and boils at 212 F.

### Conversion Shortcut

You often don't need an exact conversion. If you're traveling to Europe, for example, and you know the temperature is 74 F, you might want to know the approximate temperature in Celsius. The website Lifehacker offers this tip on making an approximate conversion:

Fahrenheit to Celsius: Subtract 30 from the Fahrenheit temperature and then divide by two. So, using the approximation formula:

• 74 F – 30 = 44
• 44 / 2 = 22 C

(If you go through the previous formula's calculations for the exact temperature, you arrive at 23.3.)

Celsius to Fahrenheit: To reverse the approximation and convert from 22 C to Fahrenheit, multiply by two and add 30. So:

• 22 C x 2 = 44
• 44 + 30 = 74 C

### Quick Conversion Table

You can save even more time by using predetermined conversions. The Old Farmer's Almanac offers this table for making quick conversions from Fahrenheit to Celsius.

Note how the Fahrenheit and Celsius scales read the same temperature at -40.

### Invention of Fahrenheit

While you're mastering these conversions, it might be interesting to learn how the Fahrenheit temperature scale came into existence. The first mercury thermometer was invented by German scientist Daniel Fahrenheit in 1714. His scale divides the freezing and boiling points of water into 180 degrees, with 32 degrees as water's freezing point, and 212 as its boiling point.

On Fahrenheit's scale, zero degrees was determined as the temperature of a temperature-stable brine solution of ice, water, and ammonium chloride. He based the scale on the average temperature of the human body, which he originally calculated at 100 degrees. (As noted, it's since been adjusted to 98.6 degrees Fahrenheit.)

Fahrenheit was the standard unit of measure in most countries until the 1960s and 1970s when it was replaced with the Celsius scale in a widespread conversion to the more useful metric system. In addition to the United States and its territories, Fahrenheit is still used in the Bahamas, Belize, and the Cayman Islands for most temperature measurements.

## How do you convert Celsius to Fahrenheit and what are the hottest temperatures recorded in the UK?

THERE are two ways to measure temperature, Celsius and Fahrenheit.

The one officially used and recognised in the UK is Celsius but many other places around the world use the Fahrenheit scale. Here's how you can figure out the temp no matter the format.

### Why is there degrees Celsius and Fahrenheit?

Degrees Celsius is the most common format of temperature in the UK.

It comes from the metric system of measurement, whereas Fahrenheit is taken from the Imperial system.

The UK began the switch to the Metric system from the Imperial system in the 60s.

The Metric system started being taught in schools in 1974, meaning that most people are more familiar with Celsius than Fahrenheit.

### How do you convert Celsius to Fahrenheit?

If the temperature is 0 degrees Celsius then it will be 32 degrees Fahrenheit.

In order to convert a temperature from Celsius to Fahrenheit, multiply the °C temperature by 1.8 and add 32 to the number.

This is the answer in °F.

### How do you convert Fahrenheit to Celsius?

In order to convert degrees Fahrenheit into Celsius, first, take the °F temperature and subtract 32.

Multiply the number you are left with by five, then divide the number by nine.

This is the answer in °C.

### What was the hottest temperature ever recorded in the UK?

The hottest temperature in the UK was recorded in Gravesend, Kent on Sunday, August 10, 2003.

The temperature hit 38°C (100.6°F), topping the last record taken earlier that same day in Heathrow, where the temperature soared to 37.9°C (100.2°F).

Before that record-breaking day, the hottest temperature ever recorded in UK history was in Cheltenham in 1990; the mercury hit 37.1°C (98.8°F).

A more recent record came on June 21, 2017, when Britain had it's hottest June day for 40 years.

The temperature was recorded at Heathrow, where the thermometer hit a scorching 34.5°C (94.1°F).

That Wednesday came close to the highest June temp ever recorded - 35.6°C (96.08°F) recorded in Southampton in June 1976.

## What's the Easiest Way to Convert Fahrenheit to Celsius?

What's the difference between Celsius and Fahrenheit? It's really a quirk of history and a simple mathematical conversion. Learn the easiest way to convert Fahrenheit to Celsius as well as the reverse calculation with simple equations and a chart. thermometer in snow Celsius and Fahrenheit

### Converting Fahrenheit to Celsius

Some would consider a quick estimate the easiest way to convert a Fahrenheit temperature to a Celsius temperature. Others want a more precise answer quickly. Here, you can learn both methods.

### Fahrenheit to Celsius Estimate Formula

Use this formula to get a good estimate of the Celsius temperature when converting from Fahrenheit. In this case / means divided by or to use division.

(Fahrenheit temp. [F]-30)/2 = Celsius temp.

In other words, if you’d like to convert a Fahrenheit temperature to an approximate Celsius temperature:

2. Subtract 30 from this figure (e.g., 100 - 30 = 70).
3. Divide your answer by 2 (e.g., 70 / 2 = 35).

### Fahrenheit to Celsius Exact Formula

If you want a more precise calculation, you can use the more exact formula. Using this calculation, we determine that 100 degrees Fahrenheit is equivalent to 37.78 degrees Celsius.

(F - 32) / 1.8 = C

In other words, if you'd like to convert a temperature reading in Fahrenheit to Celsius:

2. Subtract 32 from this figure (e.g., 100 - 32 = 68).
3. Divide your answer by 1.8 (e.g., 68 / 1.8 = 37.78)

### Converting Celsius to Fahrenheit

To convert Celsius to Fahrenheit, simply reverse the equation. In this case * means times, or to use multiplication.

(C * 1.8) + 32 = F

You can use this equation to show that 100 degrees Celsius is equal to 212 degrees Fahrenheit.

2. Multiply this figure by 1.8 (e.g., 100 * 1.8 = 180).
3. Add 32 to this figure (e.g., 180 + 32 = 212).

### Fahrenheit to Celsius Conversion Chart

If you really want an easy way to convert temperatures, you can use this Fahrenheit to Celsius conversion chart where the math has already been done for you.

### What's the Difference Between Fahrenheit and Celsius?

If you're from the United States, you're probably accustomed to describing temperature by Fahrenheit. A very hot summer day is 100 degrees, a pleasant spring morning is 50 degrees, and 0 degrees is ungodly cold. If you're from almost anywhere else, you likely favor Celsius, where 0 degrees is only pretty cold, 50 degrees is unspeakably hot, and 100 degrees happens on a stove, not outside.

### Are Fahrenheit and Celsius Readings Ever the Same?

If you were wondering if there is a temperature where Fahrenheit and Celsius are the same, it's at 40 below zero, also known as -40 or negative 40. At all other temperatures, the difference is history.

### History of Fahrenheit and Celsius Scales

Globally, the standard scale for everyday use is Celsius. Only the United States, islands freely associated with the US (Palau, the Marshall Islands and Micronesia), the Bahamas, the Caymans, and Liberia use Fahrenheit as their primary temperature measurement. Everybody else goes with Celsius.

### History of the Fahrenheit Scale

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit in 1724. Fahrenheit invented his scale for use with mercury thermometers, which he also invented. The Fahrenheit scale is a bit older than the Celsius scale.

### History of the Celsius Scale

The Celsius scale was created by Anders Celsius in 1745, a couple decades after Fahrenheit. Curiously, Celsius created the reverse of the modern scale, treating 0 as the boiling point of water and 100 as the freezing point of water. Other scientists, notably Carl Linnaeus, flipped it later that year, making 0 the freezing point and 100 the boiling point of water.

Since it was originally built as a scale between 0 and 100, Celsius is also called centigrade. The word "centigrade" literally describes something that consists of or is divided into 100 degrees. That said, Celsius has been the preferred nomenclature since 1948.

### The Kelvin Temperature Unit

You may have heard of temperature being measured according to kelvin. Indeed, if you're involved in the sciences, you probably use kelvin. Kelvin is a bit different than Fahrenheit and Celsius. Celsius and Fahrenheit are both temperature scales, measuring temperatures in degrees.

### History of the Kelvin Unit

Named after Lord Kelvin, a kelvin is a standard scientific unit, like a kilogram for weight or a meter for distance. The proper way to use the word, then, is not "100 degrees Kelvin" but "100 kelvin." (Note the lower case "k" in kelvin.)

1 kelvin equals 1/273.16th of the triple point of water: that is, the point at which liquid water, water vapor and solid ice can coexist. In other words, 273.16 kelvin is the exact triple point of water.

### The Importance of Kelvin

The importance of kelvin is that it measures absolute temperature: absolute zero is 0 kelvin, the temperature at which all atomic motion (which creates heat) stops. There is no thermal energy whatsoever at absolute zero.

### Kelvin Conversion Formulas

Kelvin is primarily of value to scientists, since it simplifies calculation at extreme temperatures. For your convenience, the conversion equations follow.

• To convert: Celsius to kelvin: C + 273.15 = K.
• To convert Fahrenheit to kelvin: [(F - 32) / 1.8] + 273.15 = K

You convert Celsius to Kelvin by simply adding 273.15. If the outside temperature is 10 degrees Celsius, then it is 283.15 kelvin. That's easy enough.

Fahrenheit is a bit trickier. Take your degrees Fahrenheit, subtract 32, divide by 1.8, and finally add 273.15. Here's a quick example:

1. Say it is 100 degrees Fahrenheit outside.
2. Subtract 32 from 100 to get 68.
3. Divide 68 by 1.8 to get 37.78.
4. Add 273.15 to get 310.93. Thus, 100 degrees Fahrenheit is equal to 310.93 kelvin.

### Taking Temperatures

Temperature is important! Measuring heat accurately matters in every field of human endeavor, from engineering to medicine. For more on how to manage your temperature, take a look at this automatic Celsius to Fahrenheit converter. It'll make short work of all your temperature conversions.

## Conversion of Temperature

### Quick Celsius (°C) / Fahrenheit (°F) Conversion:

measure/images/thermometer.js?mode=boxes

Type a value in either box

Or use the slider

Or the Interactive Thermometer

Or this method:

 °C to °F Divide by 5, then multiply by 9, then add 32 °F to °C Deduct 32, then multiply by 5, then divide by 9

(Explanation Below ...)

### Typical Temperatures

(only bold are exactly the same)

°C °F Description 220 430 Hot Oven 180 360 Moderate Oven 100 212 Water boils 40 104 Hot Bath 37 98.6 Body temperature 30 86 Beach weather 21 70 Room temperature 10 50 Cool Day 0 32 Freezing point of water −18 0 Very Cold Day −40 −40 Extremely Cold Day (and the same number!)

### Explanation

There are two main temperature scales:

• °C, the Celsius Scale (part of the Metric System, used in most countries)
• °F, the Fahrenheit Scale (used in the US)

They both measure the same thing (temperature!), but use different numbers:

• Boiling water (at normal pressure) measures 100° in Celsius, but 212° in Fahrenheit
• And as water freezes it measures 0° in Celsius, but 32° in Fahrenheit

Like this: Looking at the diagram, notice:

• The scales start at a different number (0 vs 32), so we will need to add or subtract 32
• The scales rise at a different rate (100 vs 180), so we will also need to multiply

And so, to convert:

from Celsius to Fahrenheit: first multiply by 180100, then add 32

from Fahrenheit to Celsius: first subtract 32, then multiply by 100180

180100 can be simplified to 95,
and 100180 can be simplified to 59, so we get this:

°C to °F:   Divide by 5, then multiply by 9, then add 32

°F to °C:   Subtract 32, then multiply by 5, then divide by 9

### Example: Convert 25° Celsius (a nice warm day) to Fahrenheit

First: 25° / 5 = 5
Then: 5 × 9 = 45
Then: 45 + 32 = 77° F

### Example: Convert 98.6° Fahrenheit (normal body temperature) to Celsius

First: 98.6° − 32 = 66.6
Then: 66.6 × 5 = 333
Then: 333 / 9 = 37° C

We can swap the order of divide and multiply if we want, but don't change the add or subtract. So this is also OK:

### Example: Convert 98.6° Fahrenheit to Celsius (again)

First: 98.6° − 32 = 66.6
Then: 66.6 / 9 = 7.4
Then: 7.4 × 5 = 37° C

(Same answer as before, was it easier or harder this way?)

We can write them as formulas:

Celsius to Fahrenheit:   (°C × 95) + 32 = °F
Fahrenheit to Celsius:   (°F − 32) × 59 = °C

### Use 1.8 instead of 9/5

9/5 is equal to 1.8, so we can also use this method:

Celsius to Fahrenheit:   °C × 1.8 + 32 = °F
Fahrenheit to Celsius:   (°F − 32) / 1.8 = °C

To make "×1.8" easier we can multiply by 2 and subtract 10%, but it only works for °C to °F:

Celsius to Fahrenheit:   (°C × 2) less 10% + 32 = °F

### Example: Convert 20° Celsius (A nice day) to Fahrenheit

• 20x2 = 40
• less 10% is 40−4 = 36
• 36+32 = 68° F

### Add 40, Multiply, Subtract 40

Since both scales cross at −40° (−40° C equals −40° F) we can:

• multiply by 5/9 (for °F to °C), or 9/5 (for °C to °F)
• subtract 40

Like this:

Celsius to Fahrenheit:   Add 40, multiply by 9/5, then subtract 40
Fahrenheit to Celsius:   Add 40, multiply by 5/9, then subtract 40

### Example: Convert 10° Celsius (A cool day) to Fahrenheit

• 10+40 = 50
• 50×9/5 = 90
• 90−40 = 50° F

To remember 9/5 for °C to °F think "F is greater than C, so there are more °F than °C"

### Quick, but Not Accurate

Celsius to Fahrenheit:   Double, then add 30
Fahrenheit to Celsius:   Subtract 30, then halve

Examples °C → °F:

• 0° C → 0+30 → 30° F (low by 2°)
• 10° C → 20+30 → 50° F (exact!)
• 30° C → 60+30 → 90° F (high by 4°)
• 180° C → 360+30 → 390° F (high by 34°, not good)

Examples °F → °C:

• 40° F → 10/2 → 5° C (almost right)
• 80° F → 50/2 → 25° C (low by about 2°)
• 120° F → 90/2 → 45° C (low by about 4°)
• 450° F → 420/2 → 210° C (low by about 22°, not good) Footnote: Temperature is a measure of how fast an object's particles are moving.
