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 prepare for the day or having knowledge for a vacation. Within the three different units to measure temp, Celsius and Fahrenheit are typically most used. As a mathematical theory, it’s easy to look at the utilizes of converting from one to another.

Let’s check out where these measures come from and the formula to convert from Fahrenheit to Celsius. Hopefully, in future when you go for a trip, you can swifty 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 metering temperatures.

Temperature is the volume employed to measure the warmth or coldness of something. It is measured with three primary units: Celsius, Fahrenheit, and Kelvin. The Celsius and Fahrenheit scales are used in majority parts of the world for daily life, while the Kelvin temp unit is more frequently used in a scientific context.

The Fahrenheit and Celsius temperatures are distinct measures as they are founded on the theories of separate persons.

The Celsius unit was founded by Anders Celsius, a Swedish scientist. He created this measure with water, establishing temperature values in accordance to the freezing point and boiling point of water. He allocated 100 degrees Celsius to the point when water boils and 0 to the freezing point of water.

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit, a German scientist. His measurement was in accordance with brine's freezing and boiling temperature, that is salty water. He allocated the point when water freezes at 32, while the moment when it boils is 212 degrees Fahrenheit.

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

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we learned more about the Fahrenheit and Celsius scales, let's turn our attention on how the conversion among them functions. As we saw previously, Celsius was founded with the freezing and boiling 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

Using water's features, we can base a link with the temperatures in the Fahrenheit and Celsius scales. Bear in mind 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 create 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 utilize it, substitute the temperature in Fahrenheit that you have to convert to Celsius.


Let's ensure that this formula works. Let’s solve for 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 know the equation to convert Fahrenheit to Celsius, let's practice] it step-by-step.

Steps to convert Fahrenheit to Celsius

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

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

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

Example 1

We can also use the conversion formulas to learn the average body temperature from Fahrenheit to Celsius.

98.6 F to C

Replace this given temp into the Celsius equation:

C = (98.6 F - 32) * (5/9)

C = 66.6 * 5/9

C = 37

As we've just seen, an average human body temp is 98.6 degrees F, or its similar in the Celsius unit, 37 degrees C.

Example 2

Let's use the Celsius conversion equation to transform a single degree Fahrenheit to Celsius. As per instruction, we will have to replace the value into the Celsius formula:

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

By figuring out the complete equation, 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 equals -17.22 degrees Celsius!
