## Kelvin

Based upon the definitions of the Centigrade scale and the experimental evidence that absolute zero is -273.15ºC

℃ =
K - 273.15

## Celsius

Although initially defined by the freezing point of water (and later the melting point of ice), the Celsius scale is now officially a derived scale, defined in relation to the Kelvin temperature scale.

Zero on the Celsius scale (0℃) is now defined as the equivalent to 273.15K, with a temperature difference of 1 deg C equivalent to a difference of 1K, meaning the unit size in each scale is the same. This means that 100℃, previously defined as the boiling point of water, is now defined as the equivalent to 373.15K.

The Celsius scale is an interval system but not a ratio system, meaning it follows a relative scale but not an absolute scale. This can be seen because the temperature interval between 20℃ and 30℃ is the same as between 30℃ and 40℃, but 40℃ does not have twice the air heat energy of 20℃.

A temperature difference of 1 deg C is the equivalent of a temperature difference 1.8°F.
