However, the English version of the text reproduoed here has been authorized by the Comité Consultatif de Thermométrie (CCI') and approved by the CIPM.The unit of Celsius temperature is the degree Celsius, symbol oC, which is by dermition equal in magnitude to the kelvin. A c1ifference of temperature may be expressed in kelvins or degrees Celsius. The International Temperature Scale of 1990 (! TS-90) dermes both International Kelvin lèmperatures, symbol Tgn, and International Celsius Temperatures, symbol t. o'The relation between Too and t. o is the same as that between T and t, ie:
