Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you’re in the world, understanding the outdoor temp is appropriate to prepare for the day or to pack for a trip. Among the three different units to measure temperature, Fahrenheit and Celsius are by far the most used. As a math theory, it’s straightforward to observe the usefulness of converting from one to the other.

Let’s look at 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 quickly convert these units without an online converter!

What Is Temperature?

The first matter to be aware regarding Celsius and Fahrenheit is that they are units for measuring temperatures.

Temperature is the magnitude utilized to calculate the warmth or coldness of an object. It is measured with three main scales: Kelvin, Celsius and Fahrenheit. The Fahrenheit and Celsius scales are employed in almost every part of the world for everyday life, while the Kelvin temp scale is more commonly employed in a technical environment.

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

The Celsius unit was founded by Anders Celsius, a Swedish scientist. He made this measure with water, setting temp values 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 point of water.

The Fahrenheit scale was invented by Daniel Gabriel Fahrenheit, a German physicist. His scale was based on brine's freezing and boiling temp, which is salty water. He designated the temperature 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 England and the United States, utilizes the Fahrenheit temperature scale.

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 within them works. As we looked into it before, Celsius was established 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 properties, we can establish a association with the temperatures in the Celsius and Fahrenheit units. Remember that the boiling point of water is when it gets to 100 degrees Celsius. We also know 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 work out this equation for Celsius and reach 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 desire to change it to Celsius.


Let's ensure that this equation works. Let’s solve for 212 F to C.

C = (212 F - 32) * (5/9)

C = 180 * 5/9

C = 100

Exactly as we expected: 212 degrees F = 100 degrees C

How to Convert from Fahrenheit to Celsius

Now that we know the equation to change 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 want to change, and subtract 32 from it.

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

3) The resulting number is same temperature in Celsius.

Example 1

We can also utilize the conversion formulas to study the general human body temperature from Fahrenheit to Celsius.

98.6 F to C

Replace 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 seen, an average human 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 one degree Fahrenheit to Celsius. As normally, we will have to plug the numbers into the Celsius equation:

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

By figuring out the complete formula, we will achieve the solution as a Celsius temp of:

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

C = -17.22

One degree Fahrenheit seems even more chilly when you comprehend that it equals -17.22 degrees Celsius!
