kilowatt hour (kW·h or kw hr) the commercial unit of electric energy. One kilowatt hour represents the amount of energy delivered a rate of 1000 watts over a period of one hour. Since the watt is 1 joule/sec and there are 3600 seconds in an hour, the kilowatt hour is equivalent to exactly 3.6 megajoules of energy, or about 3412.141 Btu, 859.846 (kilogram) Calories, or about 2.655 million foot pounds.
