 Fahrenheit: °F Celsius: °C Calculation:

## Celsius (°C) to Fahrenheit (°F) conversion/converter

Celsius to Fahrenheit conversion °C to °F conversion is actually quite easy – just double the °C figure and add 30. This should be reasonably accurate for weather temperatures. On the Fahrenheit scale, the melting point of water is 32°F and the boiling point is 212°F (at standard atmospheric pressure). This puts the boiling and freezing points of water 180 degrees apart. Therefore, a degree on the Fahrenheit scale is 1⁄180 of the interval between the freezing point and the boiling point. On the Celsius scale, the freezing and boiling points of water are 100 degrees apart. A temperature interval of 1 °F is equal to an interval of 5⁄9 degrees Celsius.

 Fahrenheit temperature conversion formulae from Fahrenheit to Fahrenheit Celsius [°C] = ([°F] − 32) × 5⁄9 [°F] = [°C] × 9⁄5 + 32 Kelvin [K] = ([°F] + 459.67) × 5⁄9 [°F] = [K] × 9⁄5 − 459.67 Rankine [°R] = [°F] + 459.67 [°F] = [°R] − 459.67 For temperature intervals rather than specific temperatures, 1 °F = 1 °R = 5⁄9 °C = 5⁄9 K

## 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
