joule (J),

(jūl),
A unit of energy; the heat generated, or energy expended, by an ampere flowing through an ohm for 1 sec; equal to 107 ergs and to a newton-meter. It is an approved multiple of the SI fundamental unit of energy, the erg, and is intended to replace the calorie (4.184 J).

joule

A unit of work, energy and heat. A watt-second. The joule is being used increasingly to replace the CALORIE in nutritional contexts. The calorie is equal to 4.187 J. (James Prescott Joule, 1818–89, English physicist).

joule

an SI unit of energy equal to 107 ergs or 0.239 cals. Named after the physicist J.P. Joule (1818–89) who determined the mechanical equivalent of heat and showed that 4.2×107 ergs = 1 calorie (4.2 joules = 1 cal.).
