Fahrenheit to Celsius Formula, Examples | Convert F to C

Nevertheless where you are in the world, having knowledge of the outdoor temp is appropriate to practice for the day or having knowledge for a vacation. Out of the three units to measure temperature, Fahrenheit and Celsius are usually most ordinarily used. As a math concept, it’s straightforward to look at 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. Optimistically, in future when you go for a trip, you can swifty convert these units without an online converter!

What Is Temperature?

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

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

The Celsius and Fahrenheit temps are different scales due to the fact they are based on the thesis of distinct persons.

The Celsius scale was created by Anders Celsius, a Swedish scientist. He made this scale with water, founding temperature units keep in mind the freezing point and boiling point of water. He allocated 100 degrees Celsius to signify when water boils and 0 to the freezing point of water.

The Fahrenheit scale was founded by Daniel Gabriel Fahrenheit, a German physicist. His scale was based on brine's freezing and boiling point, which is salty water. He assigned the point when water freezes at 32, while the point when it boils is 212 degrees Fahrenheit.

Most countries determine temperature in Celsius, but English-speaking countries, namely England and the United States, use the Fahrenheit temperature unit.

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 within them works. As we saw previously, Celsius was founded with the boiling and freezing 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

Utilizing water's features, we can set a link with the temps in the Celsius and Fahrenheit units. Bear 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. Given that, we can create the following equation:

100 Celsius = 212 Fahrenheit

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

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

This is the equation for conversion from Fahrenheit and Celsius. To utilize it, put the temp in Fahrenheit that you want to convert to Celsius.


Let's make sure 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

Precisely as expected: 212 degrees F = 100 degrees C

How to Convert from Fahrenheit to Celsius

Now that we understand the equation to change Fahrenheit to Celsius, let's walkthrough] it step-by-step.

Steps to convert Fahrenheit to Celsius

1) Primarily, take the temperature in Fahrenheit that you have to change, and subtract 32 from it.

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

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

Example 1

We can furthermore use the conversion formulas to study the general human body temperature from Fahrenheit to Celsius.

98.6 F to C

Replace this provided temperature into the Celsius formula:

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

C = 66.6 * 5/9

C = 37

As we've just seen, the normal human body temp is 98.6 degrees F, or its equivalent in the Celsius scale, 37 degrees C.

Example 2

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

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

By solving the whole formula, we will get the answer as a Celsius temperature of:

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

C = -17.22

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