What Is Celsius?
The temperature scale most of the world uses: water freezes at 0 and boils at 100 at sea level. In technical terms: A temperature scale defined by the kelvin: degrees C = K minus 273.15; approximately 0 degrees C at the ice point and 100 degrees C at the boiling point of water at 1 atm.
Also called: Centigrade

The Technical Definition
A temperature scale defined by the kelvin: degrees C = K minus 273.15; approximately 0 degrees C at the ice point and 100 degrees C at the boiling point of water at 1 atm. Degrees F = 1.8 times degrees C plus 32.
