A unit of work which is equal to 107 units of work in the C. G. S. system of units (ergs), and is practically equivalent to the energy expended in one second by an electric current of one ampere in a resistance of one ohm. One joule is approximately equal to 0.738 foot pounds.
- The International System unit of electrical, mechanical, and thermal energy.
- A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second.
- A unit of energy equal to the work done when a force of one newton acts through a distance of one meter. See Table at measurement.
