AnswerA watt-hour is a measure of watts * time. One watt-hour is the amount of energy used by something drawing one wattbeing used for one hour. The kilowatt hour(symbol kW·h, kW h or kWh) is a unit of energy.

Energy delivered by electric utilities is usually expressed and charged for in kWh.
Note that the kWh is the product of power in kilowatts multiplied by time in hours; it is not kW/h.
Also note that watt is the rate at which energy is flowing.
For simplicity it means that a 1000 W device will consume 1 kWh in exactly 1 hour.
Also a 100 W bulb will consume 1 kWh in 10 hours.
(Watt is like speed and kWh is like distance )

Watts are units for measuring the rate of energy consumption. So it is meaningless to speak of how many watts something consumes in a length of time. (It would be like asking how many miles per hour a car drives in an hour.)Energy consumption may be measured in kilowatt-hours. A typical microwave consumes 1500 watts, which would be 1.5 kilowatt-hours in one hour.
