How to convert Fahrenheit to Celsius
0 degrees Fahrenheit is equal to -17.7778 degrees Celsius. 32°F is the freezing point of water.
T(°C) = (T(°F) − 32) × 5/9
The temperature T in degrees Celsius (°C) is equal to the temperature T in degrees Fahrenheit (°F) minus 32, times 5/9:
T(°C) = (T(°F) − 32) × 5/9
Example
Convert 68°F to Celsius:
T(°C) = (68°F − 32) × 5/9 = 20°C
