Celsius

Temperature scale, with the freezing point of water given the value of 0 degrees (00C) and the boiling point of water 100 degrees (1000C). The unit, ‘degree Celsius’ has been known in Britain till recently as the ‘degree Centigrade’. To avoid confusion with a unit used in some other countries having the same name but used to denote fractions of a right angle, it has been agreed internationally that the name ‘degree Centigrade’ shall be replaced by ’degree Celsius’. See also Degree Fahrenheit.
