Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you’re in the world, knowing the outdoor temperature is appropriate to practice for the day or having knowledge for a trip. Within the three different scales to calculate temp, Celsius and Fahrenheit are by far the most common. As a mathematical concept, it’s simple to observe the benefits of converting from one to another.

Let’s check out where these units come from and the formula to convert from Fahrenheit to Celsius. If you get this right, later when you take a vacation, you can promptly convert these units without an online converter!

What Is Temperature?

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

Temperature is the volume utilized to measure the hotness or coldness of things. It is calculated with three primary scales: Kelvin, Celsius and Fahrenheit. The Fahrenheit and Celsius scales are employed in most part of the world for routine life, whereas the Kelvin temperature scale is more commonly used in a technical context.

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

The Celsius scale was invented by Anders Celsius, a Swedish scientist. He created this scale with water, setting temp units keep in mind the freezing point and boiling point of water. He allocated 100 degrees Celsius to the point when water boils and 0 to the freezing temp of water.

The Fahrenheit scale was invented by Daniel Gabriel Fahrenheit, a German physicist. His scale was in accordance with brine's freezing and boiling point, which is salty water. He allocated the temperature when water freezes at 32, while the temperature 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 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 works. As we looked into it before, Celsius was founded with the boiling and freezing temperatures of water being 0 and 100 degrees Celsius. These units are as same as 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

Utilizing water's characteristics, we can establish a association with the temps in the Fahrenheit and Celsius scales. Keep 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. Given that, we can set up the following equation:

100 Celsius = 212 Fahrenheit

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

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

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


Let's make sure that this formula works as intended. Let’s figure out 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 understand the formula to convert Fahrenheit to Celsius, let's practice] it one-by-one.

Steps to convert Fahrenheit to Celsius

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

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

3) The resulting number is same temp in Celsius.

Example 1

We can furthermore use the conversion formulas to study the regular body temp from Fahrenheit to Celsius.

98.6 F to C

Put 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 observed, a regular human body temp 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 a single degree Fahrenheit to Celsius. As per instruction, we would have to replace the value into the Celsius equation:

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

By figuring out the whole formula, we will end up with a Celsius temperature of:

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

C = -17.22

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