Fahrenheit to Celsius Formula, Examples | Convert F to C

Nevertheless where you’re in the world, having knowledge of the outdoor temp is applicable to practice for the day or to pack for a trip. Among the three different units to calculate temperature, Celsius and Fahrenheit are usually most used. As a mathematical concept, it’s easy to look at the benefits of converting from one to the other.

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

What Is Temperature?

The primary thing to know about Fahrenheit and Celsius is that they are units for measuring temperatures.

Temperature is the volume utilized to measure the hotness or coldness of something. It is measured with three main units: Kelvin, Celsius and Fahrenheit. The Fahrenheit and Celsius units are used in almost every part of the world for everyday life, whereas the Kelvin temperature scale is more generally employed in a technical setting.

The Fahrenheit and Celsius temps are distinct scales because they are in accordance with the theories of separate persons.

The Celsius scale was invented by Anders Celsius, a Swedish scientist. He made this measure with water, establishing temperature units based on the freezing point and boiling point of water. He assigned 100 degrees Celsius to signify when water boils and 0 to the freezing temp of water.

The Fahrenheit scale was invented by Daniel Gabriel Fahrenheit, a German physicist. His measurement was in accordance with brine's freezing and boiling temperature, which is salty water. He designated the temp when water freezes at 32, while the point when it boils is 212 degrees Fahrenheit.

Maximum countries measure temperature in Celsius, but English-speaking countries, in particular the United States and England, utilizes the Fahrenheit temperature unit.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we understand more regarding the Celsius and Fahrenheit measures, let's turn our attention on how the conversion among them works. As we observed before, Celsius was established with the boiling and freezing points of water being 0 and 100 degrees Celsius. These units correspond 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 temps in the Celsius and Fahrenheit scales. Remember 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 this, we can set up the following equation:

100 Celsius = 212 Fahrenheit

We can solve this equation for Celsius and reach the following equation:

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

This is the equation for conversion from Fahrenheit and Celsius. To utilize it, put the temperature in Fahrenheit that you have to change it to Celsius.


Let's make sure that this equation works as intended. Let’s solve for 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 know the formula to change Fahrenheit to Celsius, let's go through] it step-by-step.

Steps to convert Fahrenheit to Celsius

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

2) Subsequently, multiply that number by 5/9.

3) The resulting number is exactly the same temp in Celsius.

Example 1

We can furthermore use the conversion equations to understand the regular body temp 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 seen, a regular human body temperature is 98.6 degrees F, or its equivalent in the Celsius scale, 37 degrees C.

Example 2

Let's utilize the Celsius conversion equation to transform one degree Fahrenheit to Celsius. As usual, we would have to plug the numbers into the Celsius formula:

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

By solving the entire equation, we will achieve the solution as a Celsius temperature of:

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

C = -17.22

One degree Fahrenheit is even colder when you understand that it equals -17.22 degrees Celsius!
