Fahrenheit to Celsius Formula, Examples | Convert F to C

Nevertheless where you’re in the world, knowing the outside temperature is relevant to practice for the day or to pack for a trip. Within the three different scales to calculate temp, Fahrenheit and Celsius are typically most used. As a mathematical concept, it’s simple to look at the benefits of converting from one to the other.

Let’s check out where these scales come from and the formula to convert from Fahrenheit to Celsius. If you get this right, later when you travel, you can swifty convert these units without an online converter!

What Is Temperature?

The primary information to know regarding Celsius and Fahrenheit is that they are units for metering temps.

Temperature is the magnitude used to calculate the warmth or coldness of things. It is calculated with three main scales: Fahrenheit, Kelvin and Celsius. The Fahrenheit and Celsius units are employed in almost every part of the world for everyday life, while the Kelvin temperature unit is more generally utilized in a technical environment.

The Celsius and Fahrenheit temperatures are distinct scales because they are founded on the work of separate persons.

The Celsius scale was created by Anders Celsius, a Swedish scientist. He created this scale with water, setting temp units keep in mind 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 created by Daniel Gabriel Fahrenheit, a German scientist. 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.

Most countries determine temperature in Celsius, but English-speaking countries, namely England and the United States, use the Fahrenheit temperature unit.

What Is the Formula for Converting Fahrenheit to Celsius?

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

Formula to Convert to Celsius scale

Using water's features, we can establish a link with the temperatures in the Celsius and Fahrenheit scales. Bear in mind that the boiling point of water is when it reaches 100 degrees Celsius. We also know 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 reach the following equation:

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

This is the equation for conversion from Fahrenheit and Celsius. To use it, put the temperature in Fahrenheit that you want to change it to Celsius.


Let's ensure that this equation works. Let’s work out 212 F to C.

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

C = 180 * 5/9

C = 100

As intended we get: 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) Mainly, take the temp in Fahrenheit that you want to change, and subtract 32 from it.

2) Then, multiply that value by 5/9.

3) The answer is the equivalent temp in Celsius.

Example 1

We can furthermore use the conversion equations to study the general human body temperature from Fahrenheit to Celsius.

98.6 F to C

Put this provided temp into the Celsius equation:

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

C = 66.6 * 5/9

C = 37

As we've just observed, an average body temperature is 98.6 degrees F, or its equivalent 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 per instruction, we would have to put the value into the Celsius formula:

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

By working out the complete equation, we will end up with a Celsius temperature of:

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

C = -17.22

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