Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you are in the world, having knowledge of the outdoor temp is relevant to prepare for the day or to pack for a vacation. Among the three different units to calculate temperature, Fahrenheit and Celsius are by far the most ordinarily used. As a math concept, it’s straightforward to look at the benefits of converting from one to another.

Let’s take a look where these units come from and the formula to convert from Fahrenheit to Celsius. Hopefully, next time you travel, you can promptly convert these units without using a converter online!

What Is Temperature?

The first information to learn about Fahrenheit and Celsius is that they are units for measuring temps.

Temperature is the magnitude used to measure the hotness or coldness of an object. It is calculated with three main scales: Fahrenheit, Kelvin and Celsius. The Fahrenheit and Celsius units are used in almost every part of the world for daily life, while the Kelvin temperature scale is more frequently employed in a scientific context.

The Celsius and Fahrenheit temps are different measures because they are founded on the theories of different people.

The Celsius unit was created by Anders Celsius, a Swedish scientist. He made this scale with water, setting 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 invented by Daniel Gabriel Fahrenheit, a German scientist. His measurement was in accordance with brine's freezing and boiling temp, which is salty water. He allocated the point when water freezes at 32, while the point when it boils is 212 degrees Fahrenheit.

Most countries determine temperature in Celsius, but English-speaking countries, specifically England and the United States, utilizes the Fahrenheit temperature scale.

What Is the Formula for Converting Fahrenheit to Celsius?

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

Formula to Convert to Celsius scale

Utilizing water's properties, we can establish a association with the temps in the Fahrenheit and Celsius units. 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. Given that, we can set up the following equation:

100 Celsius = 212 Fahrenheit

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

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

This is the formula for conversion from Fahrenheit and Celsius. To use it, substitute the temperature in Fahrenheit that you desire to convert to Celsius.


Let's make sure that this equation functions. Let’s work 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 know the equation to convert Fahrenheit to Celsius, let's practice] it one-by-one.

Steps to convert Fahrenheit to Celsius

1) First, take the temp in Fahrenheit that you want to change, and subtract 32 from it.

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

3) The resulting number is same temperature in Celsius.

Example 1

We can furthermore use the conversion formulas to understand the regular human body temperature from Fahrenheit to Celsius.

98.6 F to C

Replace this specified temp into the Celsius equation:

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

C = 66.6 * 5/9

C = 37

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

Example 2

Let's use the Celsius conversion formula to transform one degree Fahrenheit to Celsius. As normally, we will have to put the numbers into the Celsius formula:

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

By figuring out the complete equation, we will get the answer as a Celsius temperature of:

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

C = -17.22

One degree Fahrenheit is even colder when you comprehend that it equals -17.22 degrees Celsius!
