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.

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.

How to convert Celsius to Fahrenheit

0 degrees Celsius is equal to 32 degrees Fahrenheit:

0 °C = 32 °F

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

Fahrenheit = Celsius × 9/5 + 32

or

Fahrenheit = Celsius × 1.8 + 32

Example

Convert 20 degrees Celsius to degrees Fahrenheit:

Fahrenheit = 20°C × 9/5 + 32 = 68 °F
