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 vacation. Among the three different units to calculate temperature, Fahrenheit and Celsius are typically most used. As a math theory, it’s simple to observe the utilizes of converting from one to another.

Let’s take a look where these measures come from and the formula to convert from Fahrenheit to Celsius. Optimistically, next time you take a vacation, you can swifty convert these units without an online converter!

What Is Temperature?

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

Temperature is the magnitude utilized to measure the hotness or coldness of something. It is measured with three primary scales: Celsius, Fahrenheit, and Kelvin. The Fahrenheit and Celsius units are used in majority parts of the world for routine life, on other hand the Kelvin temp scale is more commonly used in a technical context.

The Celsius and Fahrenheit temps are distinct measures as they are founded on the work of different individuals.

The Celsius scale was created by Anders Celsius, a Swedish scientist. He invented this scale with water, setting temp 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 created by Daniel Gabriel Fahrenheit, a German physicist. His measurement was founded on brine's freezing and boiling temp, that is salty water. He designated the temp when water freezes at 32, while the point when it boils is 212 degrees Fahrenheit.

Most countries measure temperature in Celsius, but English-speaking countries, specifically England and the United States, use the Fahrenheit temperature scale.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we understand more regarding the Celsius and Fahrenheit scales, let's turn our attention on how the conversion between them works. As we saw before, Celsius was established with the boiling and freezing temperatures 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 properties, we can establish a relationship with the temps in the Fahrenheit and Celsius scales. Remember 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. From here, we can set up the following equation:

100 Celsius = 212 Fahrenheit

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

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

This is the equation for conversion from Fahrenheit and Celsius. To utilize it, replace the temperature in Fahrenheit that you desire to convert to Celsius.


Let's ensure that this equation works as intended. Let’s figure out 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 understand the formula to change Fahrenheit to Celsius, let's walkthrough] it one-by-one.

Steps to convert Fahrenheit to Celsius

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

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

3) The resulting number is same temperature in Celsius.

Example 1

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

98.6 F to C

Put this given temp 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 temperature is 98.6 degrees F, or its similar in the Celsius unit, 37 degrees C.

Example 2

Let's utilize the Celsius conversion formula to transform a single degree Fahrenheit to Celsius. As normally, we would have to put the numbers into the Celsius equation:

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

By working out the complete equation, we will get the answer as a Celsius temp of:

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

C = -17.22

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