Frequently asked questions
How many watts are in a kilowatt?
1 kW = 1,000 W. Multiply kilowatts by 1000 (or use W = kW × 1000).
How do I convert kilowatts to watts?
Use W = kW × 1000. For example, 1 kW = 1,000 W and 10 kW = 10,000 W.
How many watts is one horsepower?
Mechanical horsepower is 745.7 W; metric horsepower (PS) is 735.5 W.
