Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you’re in the world, understanding the outdoor temperature is appropriate to prepare for the day or to pack for a vacation. Within the three different units to calculate temp, Celsius and Fahrenheit are by far the most common. As a math theory, it’s simple to see the benefits of converting from one to the other.

Let’s look at where these scales come from and the formula to convert from Fahrenheit to Celsius. If you get this right, in future when you go for a trip, you can quickly convert these scales without using a converter online!

What Is Temperature?

The first information to be aware regarding Fahrenheit and Celsius is that they are scales of metering temperatures.

Temperature is the magnitude employed to measure the warmth or coldness of something. It is measured with three primary scales: Kelvin, Celsius and Fahrenheit. The Fahrenheit and Celsius scales are used in most part of the world for daily life, whereas the Kelvin temperature scale is more commonly used in a technical environment.

The Fahrenheit and Celsius temps are different scales as they are based on the thesis of separate persons.

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

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit, a German physicist. His measurement was in accordance with brine's freezing and boiling point, that is salty water. He designated 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 the United States and England, utilizes the Fahrenheit temperature unit.

What Is the Formula for Converting Fahrenheit to Celsius?

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

Formula to Convert to Celsius scale

Using water's properties, we can set a association with the temperatures in the Fahrenheit and Celsius units. Bear 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. From this, we can create the following equation:

100 Celsius = 212 Fahrenheit

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

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

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


Let's make sure that this equation works as intended. Let’s work out 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 convert Fahrenheit to Celsius, let's go through] it step-by-step.

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 value by 5/9.

3) The resulting number is same temperature in Celsius.

Example 1

We can moreover utilize the conversion formulas to study the regular body temperature from Fahrenheit to Celsius.

98.6 F to C

Replace 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 observed, an average 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 equation to transform a single degree Fahrenheit to Celsius. As normally, we would have to plug the numbers into the Celsius formula:

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

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

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

C = -17.22

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