Fahrenheit to Celsius Formula, Examples | Convert F to C

Nevertheless where you’re in the world, knowing the outside temp is relevant to prepare for the day or to pack for a trip. Among the three different units to calculate temperature, Fahrenheit and Celsius are typically most common. As a math theory, it’s simple to observe the benefits of converting from one to another.

Let’s look at where these scales come from and the equation to convert from Fahrenheit to Celsius. Hopefully, next time you go for a trip, you can swifty convert these units without searching online!

What Is Temperature?

The primary information to know regarding Celsius and Fahrenheit is that they are scales of measuring temperatures.

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

The Celsius and Fahrenheit temperatures are distinct measures due to the fact they are founded on the thesis of separate individuals.

The Celsius scale was created by Anders Celsius, a Swedish scientist. He made this measure with water, setting temp values based on the freezing point and boiling point of water. He designated 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 physicist. His scale was based on brine's freezing and boiling temp, that is salty water. He designated the temperature when water freezes at 32, while the temp when it boils is 212 degrees Fahrenheit.

Majority of countries determine temperature in Celsius, but English-speaking countries, namely the United States and England, utilizes the Fahrenheit temperature unit.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we learned more regarding the Fahrenheit and Celsius scales, let's focus on how the conversion within them functions. As we saw previously, Celsius was founded with the freezing and boiling temperatures 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

Using water's features, we can set a link with the temps in the Fahrenheit and Celsius scales. Remember 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 this, we can make the following equation:

100 Celsius = 212 Fahrenheit

We can work out 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 want to convert 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

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

How to Convert from Fahrenheit to Celsius

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

Steps to convert Fahrenheit to Celsius

1) Primarily, take the temp in Fahrenheit that you have to change, and subtract 32 from it.

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

3) The ensuing value is the equivalent temperature in Celsius.

Example 1

We can also utilize the conversion equations to study the average body temperature 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, a regular human body temp 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 a single degree Fahrenheit to Celsius. As usual, we will have to plug the numbers into the Celsius formula:

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

By solving the entire equation, we will get the answer as a Celsius temperature of:

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

C = -17.22

One degree Fahrenheit seems even more chilly when you understand that it equals -17.22 degrees Celsius!
