The easiest method to use when converting Fahrenheit into Celsius is by using the following formula.
Regardless of the Fahrenheit temperature that you are converting into Celsius, this formula will work every time.
(F − 32) × 5/9 = C.
Here is the math explanation using 100 degrees Fahrenheit as an example.
100 Fahrenheit – 32 = 68
68 x 5 = 340
This means that 100 degrees Fahrenheit equals 37.778 degrees Celsius.
If you want to reverse the question and figure out how many degrees Fahrenheit are in 100 degrees Celsius, you would use the following formula.
(C x 9/5) + 32 = F.
Here is the math explanation again using 100 degrees Celsius as an example.
100 Celsius x 9 = 900
900/5 = 180
180 + 32 = 212
This means that 100 degrees Celsius equals 212 degrees Fahrenheit.
