Celsius to Fahrenheit ►

Fahrenheit

Fahrenheit is a unit of temperature.

The freezing/melting point of water is about 32 °F at a pressure of 1 atmosphere.

The symbol of Fahrenheit degrees is °F.

Celsius

Celsius or centigrade is a unit of temperature.

The freezing/melting point of water is about zero degrees celsius (0 °C) at a pressure of 1 atmosphere.

The boiling point of water is about one hundred degrees celsius (100 °C) at a pressure of 1 atmosphere.

The exact values depend on the water composition (usually the amount of salt) and the air pressure.

Seawater contains salt and the freezing point is reduced below 0 °C.

When boiling water on a mountain above sea level the boiling point is reduced below 100 °C.

The symbol of Celsius degrees is °C.

How to convert Fahrenheit to Celsius

0 degrees Fahrenheit is equal to -17.77778 degrees Celsius:

0 °F = -17.77778 °C

The temperature in degrees Celsius (°C) is equal to the temperature in degrees Fahrenheit (°F) minus 32, times 5/9:

Celsius = (Fahrenheit - 32) × 5/9

or

Celsius = (Fahrenheit - 32) / (9/5)

or

Celsius = (Fahrenheit - 32) / 1.8

Example

Convert 68 degrees Fahrenheit to degrees Celsius:

Celsius = (68°F - 32) × 5/9 = 20 °C
