Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you’re in the world, having knowledge of the outside temp is applicable to practice for the day or having knowledge for a trip. Among the three different scales to calculate temperature, Fahrenheit and Celsius are typically most common. As a math theory, it’s simple to see the usefulness of converting from one to the other.

Let’s look at where these scales come from and the equation to convert from Fahrenheit to Celsius. Hopefully, later when you go for a trip, you can swifty convert these scales without using a converter online!

What Is Temperature?

The first thing to learn regarding Celsius and Fahrenheit is that they are scales of metering temps.

Temperature is the volume used to calculate the hotness or coldness of something. It is calculated with three primary scales: Celsius, Fahrenheit, and Kelvin. The Fahrenheit and Celsius scales are employed in most part of the world for daily life, on other hand the Kelvin temperature scale is more generally used in a technical context.

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

The Celsius unit was invented by Anders Celsius, a Swedish scientist. He created this measure with water, setting temp values in accordance to the freezing point and boiling point of water. He assigned 100 degrees Celsius to signify when water boils and 0 to the freezing point of water.

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit, a German physicist. His scale was founded on brine's freezing and boiling temp, that is salty water. He allocated the temperature 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 scale.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we understand more about the Fahrenheit and Celsius measures, let's concentrate on how the conversion between them functions. As we looked into it previously, Celsius was established with the freezing and boiling temperatures of water being 0 and 100 degrees Celsius. These units equivalent to 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

Utilizing water's properties, we can set a link with the temperatures in the Fahrenheit and Celsius units. Keep in mind 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 get the following formula:

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

This is the formula for conversion from Fahrenheit and Celsius. To use it, replace the temp in Fahrenheit that you have to change it to Celsius.


Let's make sure that this equation functions. 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 walkthrough] it step-by-step.

Steps to convert Fahrenheit to Celsius

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

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

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

Example 1

We can moreover use the conversion formulas to understand the general human body temperature from Fahrenheit to Celsius.

98.6 F to C

Plug this specified temp into the Celsius equation:

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

C = 66.6 * 5/9

C = 37

As we've just observed, a regular human body temperature is 98.6 degrees F, or its same in the Celsius scale, 37 degrees C.

Example 2

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

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

By solving the entire formula, we will achieve the solution as a Celsius temp of:

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

C = -17.22

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