Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you are in the world, knowing the outside temperature is applicable to prepare for the day or to pack for a vacation. Out of the three units to calculate temperature, Fahrenheit and Celsius are by far the most ordinarily used. As a mathematical concept, it’s easy to look at the utilizes of converting from one to the other.

Let’s look at where these scales come from and the formula to convert from Fahrenheit to Celsius. Optimistically, later when you travel, you can quickly convert these scales without an online converter!

What Is Temperature?

The primary information to know regarding Celsius and Fahrenheit is that they are units for metering temps.

Temperature is the volume employed to calculate the warmth or coldness of something. It is measured with three main scales: Fahrenheit, Kelvin and Celsius. The Celsius and Fahrenheit scales are employed in almost every part of the world for daily life, while the Kelvin temperature scale is more generally utilized in a technical context.

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

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

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

Maximum countries calculate temperature in Celsius, but English-speaking countries, namely the United States and England, use the Fahrenheit temperature scale.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we know more about the Fahrenheit and Celsius measures, let's focus on how the conversion among them works. As we saw previously, Celsius was founded with the freezing and boiling temperatures of water being 0 and 100 degrees Celsius. These measures are as same as 32 F for freezing and 212 F for boiling in Fahrenheit.

Formula to Convert to Celsius scale

Utilizing water's characteristics, we can establish a association with the temperatures in the Celsius and Fahrenheit scales. Keep in mind that the boiling point of water is when it gets to 100 degrees Celsius. We also understand that the boiling point of water in Fahrenheit is 212 degrees. Given that, we can make the following equation:

100 Celsius = 212 Fahrenheit

We can solve 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, put the temp in Fahrenheit that you have to change it to Celsius.


Let's ensure that this formula functions. Let’s work out 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 learned the formula to convert Fahrenheit to Celsius, let's practice] it step-by-step.

Steps to convert Fahrenheit to Celsius

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

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

3) The answer is same temp in Celsius.

Example 1

We can furthermore use the conversion formulas to study the regular human body temp from Fahrenheit to Celsius.

98.6 F to C

Put this specified temperature 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 temperature is 98.6 degrees F, or its equivalent in the Celsius scale, 37 degrees C.

Example 2

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

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

By solving the whole equation, we will end up with a Celsius temp of:

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

C = -17.22

One degree Fahrenheit appears even more chilly when you comprehend that it as same as -17.22 degrees Celsius!
