The watt (pronounced /?w?t/; symbol: W) is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736â1819). The unit measures the rate of energy conversion. It is defined as one joule per second.
The dimension of power is energy divided by time. The SI unit of power is the watt (W), which is equal to one joule per second. Other units of power include ergs per second (erg/s), horsepower (hp), metric horsepower (PferdestÃ¤rke (PS) or cheval vapeur (CV)), and foot-pounds per minute.
