celsiusCelsius[deg]Ctemp1.0k The degree Celsius ([deg]C) is a unit of temperature named after the Swedish astronomer Anders Celsius (1701-1744), who first proposed a similar system in 1742. The Celsius scale sets 0.01 [deg]C to be at the triple point of water and a degree Celsius to be 1/273.16 of the difference in temperature between the triple point of water and absolute zero. Until 1954 the scale was defined with the freezing point of water at 0 [deg]C and the boiling point at 100 [deg]C at standard atmospheric pressure. This definition is still a close approximation to the actual definition and has lead many to wrongly refer to the scale as Centigrade. null
