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.
Watt definition. Watt is the unit of power (symbol: W). The watt unit is named after James Watt, the inventor of the steam engine. One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s. One watt is also defined as the current flow of one ampere with voltage of one volt. 1W = 1V Ã 1A
