Webjoule (J), ( jūl ), A unit of energy; the heat generated, or energy expended, by an ampere flowing through an ohm for 1 sec; equal to 10 7 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). Synonym (s): unit of heat (3) WebDefinition: Joule. The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).
