The watt (symbol: W) is the SI derived unit of power, equal to one joule per second. A human being climbing a flight of stairs is doing work at the rate of about 200 watts; a trained athlete can work at up to 900 watts for short periods. An automobile engine produces work at a rate of around 100 000 watts. A typical household, incandescent lightbulb uses 40 to 100 watts.
