Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you’re in the world, understanding the outside temperature is appropriate to practice for the day or having knowledge for a trip. Out of the three scales to calculate temperature, Celsius and Fahrenheit are typically most used. As a mathematical concept, it’s easy to see the utilizes of converting from one to another.

Let’s take a look where these units come from and the formula to convert from Fahrenheit to Celsius. Hopefully, in future when you go for a trip, you can promptly convert these units without using a converter online!

What Is Temperature?

The first matter to learn about Fahrenheit and Celsius is that they are scales of metering temperatures.

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

The Celsius and Fahrenheit temps are distinct measures as they are founded on the work of different people.

The Celsius unit was created by Anders Celsius, a Swedish scientist. He created this measure with water, establishing temp values in accordance to 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 created by Daniel Gabriel Fahrenheit, a German scientist. His measurement was in accordance with brine's freezing and boiling temp, which is salty water. He allocated the temp when water freezes at 32, while the moment when it boils is 212 degrees Fahrenheit.

Majority of countries measure temperature in Celsius, but English-speaking countries, specifically the United States and England, use the Fahrenheit temperature scale.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we learned more about the Fahrenheit and Celsius scales, let's focus on how the conversion between them functions. As we looked into it previously, Celsius was founded 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 properties, we can establish a association 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 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 work out this equation for Celsius and get the following equation:

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

This is the formula for conversion from Fahrenheit and Celsius. To use it, put the temperature in Fahrenheit that you have 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 intended we get: 212 degrees F = 100 degrees C

How to Convert from Fahrenheit to Celsius

Now that we learned the formula to change Fahrenheit to Celsius, let's walkthrough] it step-by-step.

Steps to convert Fahrenheit to Celsius

1) Mainly, take the temperature in Fahrenheit that you desire to convert, and deduct 32 from it.

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

3) The resulting number is the equivalent temperature in Celsius.

Example 1

We can moreover utilize the conversion equations to study 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 seen, an average human body temp is 98.6 degrees F, or its equivalent in the Celsius unit, 37 degrees C.

Example 2

Let's utilize the Celsius conversion formula to transform a single degree Fahrenheit to Celsius. As normally, we will have to plug the numbers into the Celsius equation:

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

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

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

C = -17.22

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