Fahrenheit to Celsius Formula, Examples | Convert F to C

Nevertheless where you’re in the world, knowing the outdoor temp is applicable to practice for the day or to pack for a vacation. Among the three different scales to calculate temp, Fahrenheit and Celsius are usually most used. As a math concept, it’s easy to observe the utilizes of converting from one to another.

Let’s check out where these scales come from and the formula to convert from Fahrenheit to Celsius. If you get this right, next time you travel, you can promptly convert these scales without using a converter online!

What Is Temperature?

The first thing to be aware about Celsius and Fahrenheit is that they are units for metering temps.

Temperature is the magnitude used to calculate the hotness or coldness of something. It is calculated with three primary units: Fahrenheit, Kelvin and Celsius. The Celsius and Fahrenheit scales are utilized in almost every part of the world for routine life, while the Kelvin temperature scale is more generally employed in a technical context.

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

The Celsius unit was created by Anders Celsius, a Swedish scientist. He invented this measure with water, founding temperature units keep in mind the freezing point and boiling point of water. He allocated 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 physicist. His measurement was in accordance with brine's freezing and boiling temp, that is salty water. He designated the temperature 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 England and the United States, use the Fahrenheit temperature unit.

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 between them functions. As we looked into it before, Celsius was founded with the freezing and boiling temperatures 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 features, we can base a link with the temperatures in the Fahrenheit and Celsius units. Bear in mind that the boiling point of water is when it gets to 100 degrees Celsius. We also know 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 achieve the following formula:

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

This is the formula for conversion from Fahrenheit and Celsius. To use it, replace the temp in Fahrenheit that you have to convert to Celsius.


Let's make sure that this formula works as intended. Let’s solve for 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) First, take the temperature in Fahrenheit that you desire to change, and deduct 32 from it.

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

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

Example 1

We can moreover utilize the conversion equations to understand the average human body temp from Fahrenheit to Celsius.

98.6 F to C

Replace this given temp into the Celsius formula:

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

C = 66.6 * 5/9

C = 37

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

Example 2

Let's utilize the Celsius conversion formula to transform one degree Fahrenheit to Celsius. As normally, we would have to put the numbers into the Celsius formula:

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

By figuring out the entire equation, we will get the answer as a Celsius temp of:

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

C = -17.22

One degree Fahrenheit seems even colder when you comprehend that it similar to -17.22 degrees Celsius!
