Fahrenheit to Celsius Formula, Examples | Convert F to C

No matter where you’re in the world, having knowledge of the outside temperature is relevant to prepare for the day or to pack for a vacation. Within the three different scales to measure temp, Fahrenheit and Celsius are by far the most used. As a math theory, it’s straightforward to observe 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, in future when you take a vacation, you can quickly convert these scales without using a converter online!

What Is Temperature?

The first matter to know regarding Fahrenheit and Celsius is that they are scales of measuring temperatures.

Temperature is the volume used to calculate the warmth or coldness of things. It is calculated with three main units: Fahrenheit, Kelvin and Celsius. The Fahrenheit and Celsius units are used in most part of the world for daily life, whereas the Kelvin temp scale is more generally utilized in a technical setting.

The Fahrenheit and Celsius temps are different measures because they are in accordance with the thesis of different individuals.

The Celsius scale was invented by Anders Celsius, a Swedish scientist. He invented this scale with water, founding temperature units based on the freezing point and boiling point of water. He assigned 100 degrees Celsius to the point when water boils and 0 to the freezing temp of water.

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

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

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we learned more regarding the Celsius and Fahrenheit measures, let's turn our attention on how the conversion among them functions. As we observed before, Celsius was founded 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 set a relationship with the temperatures in the Fahrenheit and Celsius scales. 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 make the following equation:

100 Celsius = 212 Fahrenheit

We can solve this formula for Celsius and reach the following formula:

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 desire to convert to Celsius.


Let's make sure that this equation works. Let’s solve for 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 equation to change Fahrenheit to Celsius, let's walkthrough] 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) Subsequently, multiply that value by 5/9.

3) The answer is same temp in Celsius.

Example 1

We can moreover use the conversion equations to learn the general body temp from Fahrenheit to Celsius.

98.6 F to C

Replace this given 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 body temperature is 98.6 degrees F, or its equivalent in the Celsius scale, 37 degrees C.

Example 2

Let's utilize the Celsius conversion formula to transform one degree Fahrenheit to Celsius. As usual, we will have to put the numbers into the Celsius equation:

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

By working out the whole equation, we will achieve the solution as a Celsius temperature of:

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

C = -17.22

One degree Fahrenheit appears even colder when you learn that it as same as -17.22 degrees Celsius!
