Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you are in the world, having knowledge of the outside temp is relevant to practice for the day or having knowledge for a vacation. Among the three different units to calculate temperature, Fahrenheit and Celsius are by far the most common. As a math concept, it’s easy to see the utilizes of converting from one to another.

Let’s look at where these scales come from and the equation to convert from Fahrenheit to Celsius. If you get this right, next time you travel, you can quickly convert these units without searching online!

What Is Temperature?

The primary matter to be aware regarding Celsius and Fahrenheit is that they are scales of measuring temperatures.

Temperature is the volume utilized to measure the warmth or coldness of things. It is measured with three primary scales: Celsius, Fahrenheit, and Kelvin. The Celsius and Fahrenheit units are used in most part of the world for everyday life, on other hand the Kelvin temperature scale is more commonly utilized in a technical environment.

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

The Celsius scale was founded by Anders Celsius, a Swedish scientist. He created this measure with water, founding temperature units keep in mind the freezing point and boiling point of water. He assigned 100 degrees Celsius to the point when water boils and 0 to the freezing temp of water.

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

Majority of 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 learned more about the Celsius and Fahrenheit scales, let's focus on how the conversion within them works. As we looked into it previously, Celsius was established with the boiling and freezing points 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 characteristics, we can establish a relationship with the temps in the Fahrenheit and Celsius scales. Remember 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 make the following equation:

100 Celsius = 212 Fahrenheit

We can work out this equation 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, substitute the temp in Fahrenheit that you want to change it to Celsius.


Let's ensure that this equation works. Let’s solve for 212 F to C.

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

C = 180 * 5/9

C = 100

Precisely as expected: 212 degrees F = 100 degrees C

How to Convert from Fahrenheit to Celsius

Now that we understand the equation to change Fahrenheit to Celsius, let's go through] it one-by-one.

Steps to convert Fahrenheit to Celsius

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

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

3) The ensuing value is the equivalent temp in Celsius.

Example 1

We can moreover use the conversion formulas to study the average body temperature from Fahrenheit to Celsius.

98.6 F to C

Replace this given temperature into the Celsius equation:

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

C = 66.6 * 5/9

C = 37

As we've just observed, a regular body temperature is 98.6 degrees F, or its same in the Celsius scale, 37 degrees C.

Example 2

Let's utilize the Celsius conversion equation to transform one degree Fahrenheit to Celsius. As normally, we would have to plug the value into the Celsius equation:

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

By working out the whole equation, we will end up with a Celsius temp of:

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

C = -17.22

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