Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you are in the world, understanding the outdoor temperature is applicable to practice for the day or having knowledge for a vacation. Out of the three units to calculate temp, Celsius and Fahrenheit are by far the most used. As a math theory, it’s simple to observe the benefits of converting from one to the other.

Let’s check out where these units come from and the formula to convert from Fahrenheit to Celsius. If you get this right, later when you take a vacation, you can quickly convert these units without searching online!

What Is Temperature?

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

Temperature is the magnitude employed to measure the hotness or coldness of an object. It is calculated with three primary scales: Fahrenheit, Kelvin and Celsius. The Celsius and Fahrenheit scales are employed in most part of the world for daily life, whereas the Kelvin temp unit is more generally used in a technical setting.

The Celsius and Fahrenheit temps are different measures due to the fact they are in accordance with the work of distinct people.

The Celsius unit was invented by Anders Celsius, a Swedish scientist. He created this measure with water, setting temp values in accordance to the freezing point and boiling point of water. He assigned 100 degrees Celsius to indicate when water boils and 0 to the freezing temp of water.

The Fahrenheit scale was invented by Daniel Gabriel Fahrenheit, a German scientist. His scale was based on brine's freezing and boiling temperature, which is salty water. He assigned the point when water freezes at 32, while the temperature when it boils is 212 degrees Fahrenheit.

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

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we know more regarding the Fahrenheit and Celsius scales, let's turn our attention on how the conversion within them functions. As we looked into it previously, Celsius was established with the boiling and freezing temperatures of water being 0 and 100 degrees Celsius. These units correspond to 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

Utilizing water's characteristics, we can establish a link with the temps in the Fahrenheit and Celsius scales. Keep in mind that the boiling point of water is when it reaches 100 degrees Celsius. We also understand that the boiling point of water in Fahrenheit is 212 degrees. Given that, we can create the following equation:

100 Celsius = 212 Fahrenheit

We can solve this formula for Celsius and get the following equation:

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

This is the equation for conversion from Fahrenheit and Celsius. To utilize it, put the temp in Fahrenheit that you want to convert to Celsius.


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

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

C = 180 * 5/9

C = 100

Exactly as we expected: 212 degrees F = 100 degrees C

How to Convert from Fahrenheit to Celsius

Now that we understand the formula to convert Fahrenheit to Celsius, let's walkthrough] it step-by-step.

Steps to convert Fahrenheit to Celsius

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

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

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

Example 1

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

98.6 F to C

Plug this specified temp into the Celsius formula:

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

C = 66.6 * 5/9

C = 37

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

Example 2

Let's use the Celsius conversion formula to transform one degree Fahrenheit to Celsius. As usual, we will have to plug the value into the Celsius equation:

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

By working out the whole equation, we will achieve the solution as a Celsius temperature of:

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

C = -17.22

One degree Fahrenheit appears even more chilly when you learn that it equals -17.22 degrees Celsius!
