This unit measures 1,000 watts of electrical power used within one second.

Explanation:
Power is how fast energy is used, and it's measured in watts. One watt equals one joule of energy per second. A kilowatt is simply 1000 watts. So if you’re talking about 1,000 watts of power used in one second, that describes a kilowatt. The other terms measure different things: volt is electric potential, forcing electrons to move; ohm is resistance to current; milliampere is a small unit of current. Kilowatt stands out as the unit that expresses a large amount of power, namely 1000 watts.
