Kilowatts to Watts (kW to W) Converter
1 kilowatt (kW) = 1,000 watts (W). To convert kilowatts to watts, multiply by 1,000: 100 kW × 1,000 = 100,000 W.
Quick facts
- 1 kW = 1,000 W
- 1 W = 0.001 kW
- Formula: W = kW × 1,000
- Quick estimate: multiply by about 1000
How to convert kilowatts to watts
- Take the value in kilowatts.
- Multiply it by 1,000 (the number of watts in one kilowatt).
- Round the result to the precision you need.
Worked example (an electric car motor): 100 kW × 1,000 = 100000 W.
To convert watts back to kilowatts, multiply by 0.001, or divide by 1,000.
