This converter allows you to convert watts [W] to kilowatts [kW] or kilowatts [kW] to watts [W]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 watt [W] = 0.001 kilowatts [kW]1 kilowatt [kW] = 1,000 watts [W]

Convert watts to kilowatts

There are two simple ways to convert watts [W] to kilowatts [kW]. In the first calculation method, the value in watts [W] is divided by 1,000. The second method multiplies the value in watts [W] by 0.001.

  • Kilowatts [kW] = watts [W] ÷ 1,000
  • Kilowatts [kW] = watts [W] * 0.001

Convert kilowatts to watts

Converting kilowatts [kW] to watts [W] is easy and can be done in two ways. The first method involves multiplication, whereby the value in kilowatts [kW] is multiplied by 1,000. The second variant is a division. Here, the value in kilowatts [kW] is divided by 0.001.

  • Watts [W] = kilowatts [kW] * 1,000
  • Watts [W] = kilowatts [kW] ÷ 0.001
