Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you’re in the world, knowing the outside temperature is relevant to practice for the day or to pack for a trip. Out of the three units to measure temperature, Celsius and Fahrenheit are typically most common. As a math theory, it’s simple to observe the utilizes of converting from one to the other.

Let’s take a look where these units come from and the equation to convert from Fahrenheit to Celsius. If you get this right, in future when you go for a trip, you can promptly convert these scales without searching online!

What Is Temperature?

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

Temperature is the magnitude utilized to measure the warmth or coldness of something. It is calculated with three main scales: Fahrenheit, Kelvin and Celsius. The Fahrenheit and Celsius units are used in most part of the world for everyday life, whereas the Kelvin temp unit is more frequently used in a technical setting.

The Fahrenheit and Celsius temperatures are distinct measures because they are based on the theories of separate individuals.

The Celsius scale was created by Anders Celsius, a Swedish scientist. He invented this scale with water, setting temp units 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 temp of water.

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

Majority of countries measure temperature in Celsius, but English-speaking countries, specifically the United States and England, utilizes the Fahrenheit temperature unit.

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we know more regarding the Celsius and Fahrenheit measures, let's concentrate on how the conversion within them functions. As we looked into it before, Celsius was established with the boiling and freezing points of water being 0 and 100 degrees Celsius. These measures equivalent to 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 temps in the Fahrenheit and Celsius units. Keep in mind 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 make the following equation:

100 Celsius = 212 Fahrenheit

We can work out this formula for Celsius and achieve 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 ensure that this formula works. Let’s figure 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 know the formula to change Fahrenheit to Celsius, let's practice] it one-by-one.

Steps to convert Fahrenheit to Celsius

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

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

3) The answer is the equivalent temperature in Celsius.

Example 1

We can furthermore utilize the conversion formulas to understand the general human body temperature from Fahrenheit to Celsius.

98.6 F to C

Put this provided temperature into the Celsius equation:

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

C = 66.6 * 5/9

C = 37

As we've just seen, a regular body temp is 98.6 degrees F, or its equivalent 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 will have to plug the value into the Celsius formula:

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

By solving the complete formula, we will achieve the solution as a Celsius temperature 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!
