Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you’re in the world, knowing the outside temperature is applicable to prepare for the day or to pack for a vacation. Within the three different scales to measure temperature, Fahrenheit and Celsius are usually most common. As a math concept, it’s simple to look at the usefulness of converting from one to the other.

Let’s look at where these measures come from and the equation to convert from Fahrenheit to Celsius. If you get this right, later when you take a vacation, you can swifty convert these units without using a converter online!

What Is Temperature?

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

Temperature is the volume used to measure the hotness or coldness of something. It is calculated with three primary scales: Kelvin, Celsius and Fahrenheit. The Fahrenheit and Celsius units are utilized in most part of the world for daily life, while the Kelvin temp scale is more commonly employed in a scientific context.

The Fahrenheit and Celsius temperatures are distinct scales because they are founded on the thesis of distinct individuals.

The Celsius unit was created by Anders Celsius, a Swedish scientist. He invented this scale with water, setting temperature values 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 point of water.

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit, a German physicist. His scale was based on brine's freezing and boiling temperature, which is salty water. He assigned the point when water freezes at 32, while the point when it boils is 212 degrees Fahrenheit.

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

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we know more regarding the Fahrenheit and Celsius scales, let's focus on how the conversion between 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 are as same as 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

Using water's features, we can set a relationship with the temps in the Celsius and Fahrenheit scales. Keep 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 here, we can create the following equation:

100 Celsius = 212 Fahrenheit

We can figure out this formula for Celsius and get the following equation:

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

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


Let's make sure that this equation functions. Let’s work out 212 F to C.

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

C = 180 * 5/9

C = 100

Exactly as we expected: 212 degrees F = 100 degrees C

How to Convert from Fahrenheit to Celsius

Now that we learned the equation to convert Fahrenheit to Celsius, let's practice] it step-by-step.

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 number by 5/9.

3) The answer is the equivalent temp in Celsius.

Example 1

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

98.6 F to C

Put this provided temperature into the Celsius equation:

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

C = 66.6 * 5/9

C = 37

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

Example 2

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

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

By figuring out the whole equation, 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 comprehend that it as same as -17.22 degrees Celsius!
