This is a measure of electrical power or rate of doing work, and means 1,000 watts. It is usually applied to large electrical outputs, and can be determined by multiplying the electro-motive force in volts by the current in amperes and dividing by 1,000. Thus, if the electro-motive force at the terminals of a circuit were 200 volts, and the current in the circuit 250 amperes, the output would be:

200 x 250 = 50,000 watts, or 50,000/1,000= 50 kilowatts.
