How to convert
Exact conversion factors in both directions, plus a worked example.
1 kW = 1000 W
1 W = 0.001 kW
To convert kilowatt to watt, multiply by 1000.
To convert watt to kilowatt, multiply by 0.001.
Example: convert 10 kW to W
10 × 1000 = 10000 W
About these units
Short background on the units used in this conversion.
Watt (W)
The watt is the SI unit of power — one joule of energy transferred per second.
Watts rate light bulbs, appliance nameplates, solar panels, and electrical device consumption.
Frequently asked questions
How many watts are in one kilowatt?
One kilowatt equals 1,000 watts. Multiply your kilowatts value by 1,000 to convert to watts.
What is the conversion formula?
W = kW × 1,000The reverse is
kW = W × 0.001, using the same exact factors as this converter.Is this Kilowatt to Watt converter private?
