Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you’re in the world, knowing the outdoor temp is applicable to prepare for the day or to pack for a vacation. Within the three different scales to calculate temp, Celsius and Fahrenheit are typically most used. As a mathematical theory, it’s straightforward to see the utilizes of converting from one to another.

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 take a vacation, you can swifty convert these units without an online converter!

What Is Temperature?

The primary information to learn regarding Fahrenheit and Celsius is that they are scales of metering temps.

Temperature is the volume employed to measure the warmth or coldness of an object. It is calculated with three main units: Celsius, Fahrenheit, and Kelvin. The Celsius and Fahrenheit scales are utilized in almost every part of the world for daily life, whereas the Kelvin temp scale is more commonly employed in a scientific context.

The Celsius and Fahrenheit temperatures are distinct scales as they are based on the theories of different persons.

The Celsius unit was created by Anders Celsius, a Swedish scientist. He made this scale with water, establishing temp units based on the freezing point and boiling point of water. He allocated 100 degrees Celsius to the point when water boils and 0 to the freezing temp of water.

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit, a German scientist. His scale was founded on brine's freezing and boiling temperature, that is salty water. He designated the temp 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, use the Fahrenheit temperature scale.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we know more about the Celsius and Fahrenheit measures, let's turn our attention 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 measures 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 association with the temps in the Celsius and Fahrenheit units. Remember 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. From here, we can create the following equation:

100 Celsius = 212 Fahrenheit

We can solve 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 utilize it, substitute the temperature in Fahrenheit that you want to change it to Celsius.


Let's ensure 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 change Fahrenheit to Celsius, let's practice] it one-by-one.

Steps to convert Fahrenheit to Celsius

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

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

3) The answer is the equivalent temp in Celsius.

Example 1

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

98.6 F to C

Plug 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 observed, an average human body temp is 98.6 degrees F, or its similar in the Celsius scale, 37 degrees C.

Example 2

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

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

By solving the complete equation, 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!
