How Much Is 100 Fahrenheit in Celsius?

 

100 degrees Fahrenheit is the same as 37.78 degrees in Celsius.

Converting imperial to metric units is always a challenge, but as long as you know the formula, manually converting Fahrenheit to Celsius and vice versa is a cinch.

Fahrenheit to Celsius Formula

Fahrenheit to Celsius Formula

The following formulas will show you get a Celsius figure from Fahrenheit:

C = (F – 32) × 5/9

or

C = (F – 32) ÷ 1.8

Above, you need to subtract 32 from the Fahrenheit temperature. Then either multiply the remaining figure by 5 and divide the product by 9. As an alternative, you can divide the difference between the Fahrenheit temperature and 32 by 1.8.

So, to get a Celsius number from 100 degrees in Fahrenheit, we would have to do the following:

C = (100 – 32) × 5/9

C = (68 × 5) ÷ 9

C = 340 ÷ 9

C = 37.78

or

C = (100 – 32) ÷ 1.8

C = 68 ÷ 1.8 = 37.78

To use another example, let’s take the boiling point in Fahrenheit–212 degrees–and see what it is in Celsius.

C = (212 – 32) × 5/9

C = (180 × 5) ÷ 9

C = 900 ÷ 9

C = 100

or

C = (212 – 32) ÷ 1.8

C = 180 ÷ 1.8

C = 100

Celsius to Fahrenheit Formula

Going from Celsius to Fahrenheit can be just as complex. Below, I’ll show you both formulas to do this:

F = (C ÷ (5/9)) + 32

or

F = (C × 1.8) + 32

So, assuming we wanted to know how hot 80 degrees in Celsius is in Fahrenheit terms, we would do the following:

F = (80 ÷ (5/9) + 32

F = (16 × 9) + 32

F = 144 + 32

F = 176

or

F = (80 × 1.8) + 32

F = 144 + 32

F = 176

The Only Meeting Point

There is only one point in both measurement units where they will be the same: -40 degrees. Allow me to demonstrate:

C = (-40 – 32) ÷ 1.8

C = -72 ÷ 1.8

C = -40

and

F = (-40 × 1.8) + 32

F = -72 + 32

F = -40

What Is Fahrenheit?

The Fahrenheit unit of measuring temperature was discovered by Polish-born physicist Daniel Gabriel Fahrenheit in the 1680s. At the time, the world was struggling to determine a way of consistently measuring temperature.

What Fahrenheit did was he set the zero-degree mark at the lowest temperature of saltwater. He also marked 96 degrees, which he believed was the average human body temperature, on the scale.

With these two figures, Fahrenheit determined that water freezes at 32 degrees and boils at 212 degrees.

What Is Celsius?

Celsius as a unit for measuring temperature was discovered approximately 6 decades after Fahrenheit created his temperature scale. The Swedish astronomer, Anders Celsius, invented a scale that separates the temperatures at which water freezes and boils by a factor of 100.

So, water will freeze at 0 degrees Celsius and boil at 100 degrees Celsius.
