About these units
The watt (W) is an SI base or derived unit of power.
The kilowatt (kW) is a metric unit of power, equal to 1,000 watts.
Going the other way, 1 kilowatt = 1,000 watts. Power is energy per unit time — engine output in horsepower, air-conditioning capacity in tons, appliance draw in watts. All of them convert cleanly through the watt.
