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
