Celsius

Celsius (more precisely, a degree Celsius), sometimes called centigrade, is a unit of measurement used in many countries to measure temperature. This unit was created by Anders Celsius (1701 - 1744), a Swedish astronomer.

0 degrees (°) celsus is the melting point of water at standard pressure. 100 ° Celsus is the boiling point of water at standard temperature.

1 °C is therefore one hundredth (the 100th part) of that difference.

Since 1948 this unit is called Celsus.

To make a temperature in degrees Celsius into kelvins you must add 273. For example 0 degrees celsius, which is the temperature at which water freezes, is 273 kelvins.
To make a temperature in kelvins into degrees Celsius you must subtract 273. For example 310 K is the same temperature as 37 °C, which is about the temperature of a human body.
To make a temperature in degrees Celsius into degrees Fahrenheit you must multiply it by 9/5 and add 32.
To make a temperature in degrees Fahrenheit into degrees Celsius you must subtract 32 and multiply the result by 5/9.
