Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you are in the world, having knowledge of the outside temperature is relevant to prepare for the day or to pack for a vacation. Out of the three units to measure temperature, Fahrenheit and Celsius are typically most used. As a math theory, it’s easy to look at the usefulness of converting from one to the other.

Let’s check out where these units come from and the formula to convert from Fahrenheit to Celsius. If you get this right, later when you travel, you can swifty convert these units without searching online!

What Is Temperature?

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

Temperature is the volume employed to calculate the warmth or coldness of something. It is calculated with three main units: Kelvin, Celsius and Fahrenheit. The Fahrenheit and Celsius units are used in most part of the world for daily life, while the Kelvin temp unit is more commonly used in a technical context.

The Celsius and Fahrenheit temperatures are distinct measures as they are founded on the thesis of separate persons.

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

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

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

What Is the Formula for Converting Fahrenheit to Celsius?

Now that we learned more about the Celsius and Fahrenheit measures, let's concentrate on how the conversion between them works. As we looked into it previously, Celsius was founded with the boiling and freezing temperatures 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 properties, we can set a relationship with the temps 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 understand 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 get the following equation:

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

This is the equation for conversion from Fahrenheit and Celsius. To use it, replace the temperature in Fahrenheit that you desire to convert to Celsius.


Let's make sure that this equation 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 know the equation to change Fahrenheit to Celsius, let's go through] it one-by-one.

Steps to convert Fahrenheit to Celsius

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

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

3) The ensuing value is same temp in Celsius.

Example 1

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

98.6 F to C

Replace this specified temp into the Celsius formula:

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 similar 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 would have to plug the numbers into the Celsius equation:

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 seems even more chilly when you learn that it equals -17.22 degrees Celsius!
