Joule's equivalent
joule joule (j[=oo]l), n. [From the distinguished English physicist, James Prescott Joule (1818-1889).] (Physics.) A unit of work which is equal to 10^{7} ergs (the unit of work in the C. G. S. system of units), and is equivalent to one watt-second, the energy expended in one second by an electric current of one ampere in a resistance of one ohm; also called the {absolute joule}. It is abbreviated J or j. The {international joule} is slightly larger, being 1.000167 times the absolute joule. The absolute joule is approximately equal to 0.737562 foot pounds, 0.239006 gram-calories (small calories), and 3.72506 x 10^{-7} horsepower-hours, and 0.000948451 B.t.u. --HCP61 [1913 Webster +PJC]
