Kilowatt to Watt (kW to W)
Result
1,000 Watt
Formula
W = kW × 1,000
1 kW = 1,000 W, and 1 W = 0.001 kW.
The watt is one joule per second. Mechanical horsepower is 550 foot-pound-force per second, which is 745.69987 W.
Worked examples
- 1 kW × 1,000 = 1,000 W
- 10 kW × 1,000 = 10,000 W
- 100 kW × 1,000 = 100,000 W
Common mistakes
- Horsepower comes in several sizes: mechanical (745.7 W), metric/PS (735.5 W) and electrical (746 W). Car specifications in Europe and Japan usually quote PS.
- Power (W) is a rate; energy (Wh, J) is power × time.
