1 Kwh can be defined as the amount of electrical energy consumed when a 1000 watt electrical appliance is used for an hour. The unit of energy is watt. 1 Watt = 1 Joule /second. One kilowatt hour is 3.6 megajoules. It is the amount of energy converted if work is done at the rate of 1000 watts per hour.
