## watt

(wŏt)
A unit used to measure power, equal to one joule of work per second. In electricity, a watt is equal to the amount of current (in amperes) multiplied by the amount of potential (in volts).

## watt

1. The unit of power: one watt equals one joule per second.
2. (W) A unit of power equal to that available when one joule of energy is expended in one second. 1 W = 1 volt-ampere; 746 W = 1 horsepower (hp). Named after the Scottish engineer James Watt (1736–1819).
