100 degrees Fahrenheit equals 37.778 degrees Celsius.
To convert 100 Fahrenheit into Celsius, you need to use the following formula.
(F − 32) × 5/9 = C.
Here is the math explanation.
100 Fahrenheit – 32 = 68
68 x 5 = 340
340/9 =37.778
This means that 100 degrees Fahrenheit equals 37.778 degrees Celsius.
If you want to reverse the question and figure out how degrees Fahrenheit are in 100 degrees Celsius, you would use the following formula.
(C x 9/5) + 32 = F.
Here is the math explanation.
100 Celsius x 9 = 900
900/5 = 180
180 + 32 = 212
This means that 100 degrees Celsius equals 212 degrees Fahrenheit.
