Quick Answer
1 kW = 1.34102 hp
Formula: Horsepower = Kilowatt x 1.34102
Quick values
What is horsepower and kilowatts?
Horsepower and kilowatts both measure power, the rate of doing work. Mechanical (imperial) horsepower is 745.69987 watts; a kilowatt is 1,000 watts.
FormulakW = hp × 0.74569987
Key conversions
- 1 hp = 0.74569987 kW (mechanical horsepower)
- 1 kW = 1.341022 hp
- Metric horsepower (PS) is 735.49875 W, slightly smaller than mechanical hp
- Use watts or kilowatts in SI calculations; hp remains common on nameplates
