Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you’re in the world, having knowledge of the outdoor temperature is relevant to practice for the day or to pack for a trip. Among the three different scales to calculate temperature, Celsius and Fahrenheit are typically most common. As a math theory, it’s straightforward to look at the benefits of converting from one to the other.

Let’s check out where these scales come from and the equation to convert from Fahrenheit to Celsius. Optimistically, later when you go for a trip, you can quickly convert these units without an online converter!

What Is Temperature?

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

Temperature is the volume employed to calculate the hotness or coldness of things. It is calculated with three main units: Celsius, Fahrenheit, and Kelvin. The Celsius and Fahrenheit scales are employed in majority parts of the world for daily life, whereas the Kelvin temperature unit is more frequently utilized in a scientific environment.

The Fahrenheit and Celsius temperatures are distinct scales as they are in accordance with the theories of different individuals.

The Celsius scale was invented by Anders Celsius, a Swedish scientist. He created this measure with water, establishing temperature values keep in mind 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 founded by Daniel Gabriel Fahrenheit, a German physicist. His scale was in accordance with brine's freezing and boiling point, which is salty water. He designated the point when water freezes at 32, while the temperature when it boils is 212 degrees Fahrenheit.

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

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 within them functions. As we looked into it previously, Celsius was founded 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

Utilizing water's features, we can establish a relationship with the temps in the Celsius and Fahrenheit units. Bear in mind that the boiling point of water is when it gets to 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 work out this formula for Celsius and achieve the following equation:

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

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


Let's make sure that this formula 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 know the equation to change Fahrenheit to Celsius, let's practice] it step-by-step.

Steps to convert Fahrenheit to Celsius

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

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

3) The answer is exactly the same temperature in Celsius.

Example 1

We can moreover utilize the conversion formulas to learn the general human body temp from Fahrenheit to Celsius.

98.6 F to C

Plug this specified 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 body temperature is 98.6 degrees F, or its same in the Celsius scale, 37 degrees C.

Example 2

Let's use the Celsius conversion equation to transform one degree Fahrenheit to Celsius. As normally, we would have to replace 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 is even colder when you understand that it equals -17.22 degrees Celsius!
