How to convert 70 degrees Fahrenheit to Celsius.
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 = (70°F - 32) × 5/9 = 21.111°C
So 70 degrees Fahrenheit are equal to 21.111 degrees Celsius:
70°F = 21.111°C
