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 main way electricity consumption is measured is with the unit âwatt-hourâ. A watt (W) is a measure of electrical power. Light bulbs are marked with a watt rating, such as 40 W, and so are appliances like air-blow heaters (around 1,000 W). In fact, most appliances have a compliance badge that will give you an indication of the amount of electrical power it needs to work.
