Watts to kilowatts

1 watt in kilowatts
1 W = 0.001 kW
kW = W × 0.001

To convert watts to kilowatts, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is kW = W × 0.001. Both units measure power, so the conversion is a fixed factor that never changes.

Common questions

How many kilowatts are in one watt?
One watt equals 0.001 kilowatts. kW = W × 0.001.
How do you convert watts to kilowatts?
Use kW = W × 0.001. So 10 W is 0.01 kW.
How many watts are in one kilowatt?
One kilowatt equals 1,000 watts, which is the reverse of the conversion above.
