How to convert kilowatts to watts
W = kW × 1,000Multiply the value in kilowatts by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A kilowatt is larger than a watt: one kilowatt contains 1,000 watts.

About the units
Kilowatt (kW)
One thousand watts. Electric-vehicle motors, home solar arrays and engines are rated in kW. One kilowatt equals 1,000 watts (W).
Watt (W)
The SI unit of power: one joule per second. An LED bulb draws around 10 W, a microwave about 1,000 W.
Frequently asked questions
How many watts are in one kilowatt?
There are 1,000 watts in one kilowatt, and this value is exact by definition.
How do I convert kilowatts to watts?
Multiply the number of kilowatts by 1,000. For example, 10 kW × 1,000 = 10,000 W.
How many kilowatts are in one watt?
One watt equals 0.001 kilowatts. That is the reverse factor, 1 ÷ 1,000.
What is 10 kilowatts in watts?
10 kW = 10,000 W.
Is this kW to W converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
