Dear Brenton and All, Table 10. Examples of other non-SI units of the BIPM brochure, 'The International System of Units (SI)' lists calorie and its symbol cal with these notes" Several "calories" have been in use: * a calorie labelled "at 15�C": 1 cal(15) = 4.1855 J (value adopted by the CIPM in 1950; PV, 1950, 22, 79-80); * a calorie labelled "IT" (International Table): 1 cal(IT) = 4.1868 J (5th International Conference on the Properties of Steam, London, 1956); * a calorie labelled "thermochemical": 1 cal(th) = 4.184 J.
Fran�ois Cardarelli lists the various calories (calorie 15 �C, calorie IT, and calorie therm) in 'Table 2.9 Non-SI units to be discontinued' in his book, 'Scientific Unit Conversion (2nd edition 1999).
