Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you are in the world, understanding the outdoor temp is relevant to prepare for the day or having knowledge for a trip. Among the three different units to calculate temp, Fahrenheit and Celsius are typically most used. As a math theory, it’s easy to observe the usefulness of converting from one to the other.

Let’s take a look where these units 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 promptly convert these scales without using a converter online!

What Is Temperature?

The primary thing to be aware about Celsius and Fahrenheit is that they are units for metering temps.

Temperature is the volume used to calculate the warmth or coldness of things. It is measured with three main scales: Celsius, Fahrenheit, and Kelvin. The Fahrenheit and Celsius units are employed in almost every part of the world for routine life, while the Kelvin temperature scale is more generally used in a scientific environment.

The Celsius and Fahrenheit temps are distinct measures due to the fact they are founded on the theories of separate people.

The Celsius scale was founded by Anders Celsius, a Swedish scientist. He invented this scale with water, founding temp values in accordance to the freezing point and boiling point of water. He designated 100 degrees Celsius to the point when water boils and 0 to the freezing point of water.

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

Maximum countries determine temperature in Celsius, but English-speaking countries, specifically the United States and England, use the Fahrenheit temperature unit.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we understand more regarding the Celsius and Fahrenheit measures, let's focus on how the conversion within them functions. As we looked into it before, Celsius was established with the freezing and boiling points of water being 0 and 100 degrees Celsius. These measures correspond to 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

Utilizing water's features, we can base a relationship with the temps in the Celsius and Fahrenheit units. Keep in mind that the boiling point of water is when it gets to 100 degrees Celsius. We also learned that the boiling point of water in Fahrenheit is 212 degrees. Given that, we can set up the following equation:

100 Celsius = 212 Fahrenheit

We can work out this formula for Celsius and get the following formula:

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

This is the equation for conversion from Fahrenheit and Celsius. To use it, put the temperature in Fahrenheit that you desire to change it to Celsius.


Let's make sure that this equation works. Let’s figure out 212 F to C.

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

C = 180 * 5/9

C = 100

As intended we get: 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 walkthrough] it step-by-step.

Steps to convert Fahrenheit to Celsius

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

2) Then, multiply that number by 5/9.

3) The resulting number is the equivalent temp in Celsius.

Example 1

We can moreover use the conversion equations to understand the general human body temp from Fahrenheit to Celsius.

98.6 F to C

Replace this specified temperature into the Celsius formula:

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

C = 66.6 * 5/9

C = 37

As we've just seen, a regular human body temp is 98.6 degrees F, or its equivalent in the Celsius unit, 37 degrees C.

Example 2

Let's utilize the Celsius conversion equation to transform a single degree Fahrenheit to Celsius. As usual, we will have to put the value into the Celsius formula:

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

By working out the entire formula, we will achieve the solution as a Celsius temperature of:

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

C = -17.22

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