Watts to Kilowatts Calculator

Convert watts to kilowatts (and back) — plus megawatts and horsepower — in one step. Watts and kilowatts are both units of power; a kilowatt is simply 1,000 watts. Enter a value in any unit to see the rest.

1 kW = 1,000 W · 1 MW = 1,000,000 W · 1 hp ≈ 746 W. These are power units. For energy over time (kWh), use the watts-to-kWh converter below.

Frequently asked questions

Divide the watts by 1,000. A kilowatt (kW) is 1,000 watts, so 1,500 watts ÷ 1,000 = 1.5 kW. To go from kilowatts back to watts, multiply by 1,000.
