Fahrenheit to Celsius Formula, Examples | Convert F to C

Nevertheless where you’re in the world, having knowledge of the outdoor temperature is applicable to practice for the day or to pack for a trip. Out of the three units to measure temp, Celsius and Fahrenheit are typically most ordinarily used. As a mathematical theory, it’s straightforward to observe the usefulness of converting from one to the other.

Let’s take a look where these scales come from and the formula to convert from Fahrenheit to Celsius. If you get this right, next time you go for a trip, you can swifty convert these scales without searching online!

What Is Temperature?

The primary thing to learn regarding Fahrenheit and Celsius is that they are units for metering temps.

Temperature is the magnitude used to calculate the warmth or coldness of an object. It is measured with three primary scales: Celsius, Fahrenheit, and Kelvin. The Fahrenheit and Celsius units are employed in almost every part of the world for everyday life, on other hand the Kelvin temp scale is more commonly employed in a technical setting.

The Fahrenheit and Celsius temps are different scales due to the fact they are founded on the work of distinct individuals.

The Celsius scale was invented by Anders Celsius, a Swedish scientist. He made this measure with water, establishing temp units in accordance to the freezing point and boiling point of water. He allocated 100 degrees Celsius to signify when water boils and 0 to the freezing temp of water.

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit, a German physicist. His scale was in accordance with brine's freezing and boiling point, which is salty water. He designated the temp when water freezes at 32, while the point when it boils is 212 degrees Fahrenheit.

Most countries calculate temperature in Celsius, but English-speaking countries, in particular England and the United States, use the Fahrenheit temperature unit.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we know more about the Fahrenheit and Celsius scales, let's turn our attention on how the conversion between them functions. As we observed before, Celsius was established with the boiling and freezing temperatures of water being 0 and 100 degrees Celsius. These units are as same as 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

Using water's characteristics, we can base a relationship with the temperatures in the Fahrenheit and Celsius scales. Bear in mind that the boiling point of water is when it reaches 100 degrees Celsius. We also learned that the boiling point of water in Fahrenheit is 212 degrees. From this, we can set up the following equation:

100 Celsius = 212 Fahrenheit

We can figure out this equation for Celsius and get the following equation:

Celsius = (Fahrenheit - 32) * (5/9)

This is the equation for conversion from Fahrenheit and Celsius. To use it, replace the temperature in Fahrenheit that you want to convert to Celsius.


Let's ensure that this formula works. Let’s figure out 212 F to C.

C = (212 F - 32) * (5/9)

C = 180 * 5/9

C = 100

As expected: 212 degrees F = 100 degrees C

How to Convert from Fahrenheit to Celsius

Now that we understand the formula to change Fahrenheit to Celsius, let's practice] it one-by-one.

Steps to convert Fahrenheit to Celsius

1) Mainly, take the temp in Fahrenheit that you have to convert, and subtract 32 from it.

2) Next, multiply that value by 5/9.

3) The ensuing value is exactly the same temperature in Celsius.

Example 1

We can also utilize the conversion equations to study the average human body temp from Fahrenheit to Celsius.

98.6 F to C

Plug this provided temperature into the Celsius formula:

C = (98.6 F - 32) * (5/9)

C = 66.6 * 5/9

C = 37

As we've just seen, the normal human body temp is 98.6 degrees F, or its same in the Celsius scale, 37 degrees C.

Example 2

Let's use the Celsius conversion equation to transform a single degree Fahrenheit to Celsius. As usual, we will have to replace the numbers into the Celsius equation:

C = (1 F - 32) * (5/9)

By working out the whole formula, we will achieve the solution as a Celsius temp of:

C = (- 31) * (5/9)

C = -17.22

One degree Fahrenheit is even more chilly when you learn that it as same as -17.22 degrees Celsius!
