'''Celsius''' is a [[temperature]] scale in the [[metric system]].  The scale was originally defined such that at standard atmospheric pressure [[water]] freezes at 0 ºC and boils at 100 ºC.  To convert from [[Fahrenheit]] to Celsius take the Fahrenheit temperature, subtract 32 then multiply by 5 and divide by 9.

One Celsius degree is equal to one [[Kelvin]], with an offset such that T(°C) = T(K) - 273,15

One Celsius degree is equal to one degree [[Kelvin]], with an offset such that T(°C) = T(K) - 273.15.  So Kelvin's [[absolute zero]] (the temperature at which there is no heat) is -273.15 degrees Celsius.

Celsius is the commonly used unit of temperature in Europe and Canada, but in the United States, Fahrenheit is still preferred. ''Centigrade'' was a term commonly used as a synonym of Celsius in the past.
