International thermometric scale on which the freezing point of water equals 0° and the boiling point equals 100° at standard atmospheric pressure (760 mm Hg). Named for Swedish astronomer Anders Celsius (1701-1744), who devised the system in 1742.
Thermodynamic scale of temperature. Temperature in degrees Celsius can be obtained from value in degrees Fahrenheit by the following formula: C = (F - 32) x 5/9
scale to measure temperature that defines the freezing point of water as 0 and the steam point as 100
