## How to convert Fahrenheit to Celsius

0 degrees Fahrenheit is equal to -17.77778 degrees Celsius:

0 °F = -17.77778 °C

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

or

T(°C) = (T(°F) - 32) / (9/5)

or

T(°C) = (T(°F) - 32) / 1.8

Example

Convert 68 degrees Fahrenheit to degrees Celsius:

T(°C) = (68°F - 32) × 5/9 = 20 °C
