Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you’re in the world, knowing the outdoor temp is applicable to practice for the day or having knowledge for a vacation. Within the three different units to calculate temp, Fahrenheit and Celsius are usually most ordinarily used. As a math concept, it’s easy to see the utilizes of converting from one to the other.

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

What Is Temperature?

The primary thing to learn regarding Celsius and Fahrenheit is that they are units for metering temperatures.

Temperature is the magnitude employed to measure the hotness or coldness of an object. It is calculated with three primary scales: Celsius, Fahrenheit, and Kelvin. The Fahrenheit and Celsius scales are utilized in majority parts of the world for routine life, whereas the Kelvin temperature scale is more commonly used in a scientific setting.

The Fahrenheit and Celsius temps are different measures due to the fact they are in accordance with the work of separate persons.

The Celsius unit was founded by Anders Celsius, a Swedish scientist. He made this scale with water, setting temp units in accordance to the freezing point and boiling point of water. He allocated 100 degrees Celsius to indicate when water boils and 0 to the freezing temp of water.

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

Maximum countries determine 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 understand more about the Celsius and Fahrenheit measures, let's turn our attention on how the conversion between them functions. As we observed before, Celsius was created with the freezing and boiling points of water being 0 and 100 degrees Celsius. These measures correspond to 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

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

100 Celsius = 212 Fahrenheit

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

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

This is the formula for conversion from Fahrenheit and Celsius. To use it, put the temp in Fahrenheit that you want 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 learned the formula to convert 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 want to convert, and subtract 32 from it.

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

3) The ensuing value is exactly the same temp in Celsius.

Example 1

We can also use the conversion equations to learn the regular human body temp from Fahrenheit to Celsius.

98.6 F to C

Put 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, the normal body temp is 98.6 degrees F, or its similar in the Celsius scale, 37 degrees C.

Example 2

Let's utilize the Celsius conversion equation to transform one degree Fahrenheit to Celsius. As per instruction, we would have to replace the numbers into the Celsius equation:

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

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

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

C = -17.22

One degree Fahrenheit seems even colder when you learn that it similar to -17.22 degrees Celsius!
