Fahrenheit to Celsius Formula, Examples | Convert F to C

Regardless where you’re in the world, having knowledge of the outdoor temperature is relevant to practice for the day or having knowledge for a trip. Within the three different units to measure temperature, Fahrenheit and Celsius are typically most ordinarily used. As a math concept, it’s easy 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 go for a trip, you can swifty convert these scales without an online converter!

What Is Temperature?

The primary matter to learn about Celsius and Fahrenheit is that they are scales of measuring temps.

Temperature is the magnitude utilized to measure the warmth or coldness of something. It is calculated with three primary scales: Celsius, Fahrenheit, and Kelvin. The Celsius and Fahrenheit units are used in most part of the world for routine life, on other hand the Kelvin temperature unit is more frequently employed in a technical context.

The Celsius and Fahrenheit temps are distinct scales due to the fact they are in accordance with the theories of separate persons.

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

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

Majority of countries determine 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 learned more regarding the Fahrenheit and Celsius measures, let's focus on how the conversion within 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

Utilizing water's properties, we can establish a link with the temps in the Fahrenheit and Celsius scales. Bear 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 create the following equation:

100 Celsius = 212 Fahrenheit

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

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

This is the formula for conversion from Fahrenheit and Celsius. To utilize it, replace the temperature in Fahrenheit that you want to convert to Celsius.


Let's make sure that this formula functions. 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 understand the equation to change 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 want to change, and deduct 32 from it.

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

3) The resulting number is exactly the same temperature in Celsius.

Example 1

We can moreover use the conversion equations to understand the regular body temp from Fahrenheit to Celsius.

98.6 F to C

Plug this provided temp into the Celsius equation:

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

C = 66.6 * 5/9

C = 37

As we've just seen, the normal human body temperature is 98.6 degrees F, or its similar in the Celsius unit, 37 degrees C.

Example 2

Let's use the Celsius conversion formula to transform a single degree Fahrenheit to Celsius. As usual, we will have to replace the numbers into the Celsius formula:

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

By working out the whole equation, we will get the answer as a Celsius temp of:

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

C = -17.22

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