Converting Fahrenheit to Celsius: A Simple Guide to Understanding Global Temperatures.
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
Convert 68 degrees Fahrenheit to degrees Celsius:
T(°C) = (68°F - 32) × 5/9 = 20 °C
