What's the formula for converting Fahrenheit to Celsius?

Answer 1

T_(°C) = (T_(°F) - 32) × 5/9

Solve for F:

Tf = Tc(9/5) + 32

Answer 2

There are several formulae to do this. Here are just 2. There are others.

F =(C × 9/5) + 32 or (°F - 32) x 5/9 = °C

Ex: 212 degrees F

(212-32) x 5/9 = 180 x 5/9 = 100 degrees C

F = 1.8C + 32 or (F-32)/1.8

Ex: 212 degrees F

(212-32)/1.8 = 180/1.8 = 100 degrees C
