The Celsius scale is used by scientists to measure temperature. 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. So absolute zero, 0 K, (the temperature at which there is no heat) is -273.15 degrees Celsius.
Celsius is the commonly used unit of temperature in Europe, Canada, Mexico, most of Asia, South America, most of Africa and Australia but in the United States, Fahrenheit is still preferred. [1]
Centigrade is a term commonly used as a synonym of Celsius, especially when giving weather temperature on the air.
