Word Origin & History

calorie 
1866, from L. calor (gen. caloris) "heat," from PIE base *kel- "warm" (cf. L. calere "be hot;" Skt. carad- "harvest," lit. "hot time;" Lith. silti "become warm," silus "August;" O.N. hlær "warm"). Technically, the heat required to raise 1 kilogram of water 1 degree Celsius. In scientific use, largely replaced 1950 by the joule. Caloric, the supposed elastic fluid that accounted for phenomena of heat in Lavoisier's now-abandoned theory, was in use from 1792.
