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.

Subject: [biofuel] electrical heating question


While we're on the subject of electricity, I got a question about heating
elements: in an electric water heater element, is there an easy way to
predict the BTU output produced, based on the rated wattage?
