Horsepower to Kilowatts Converter
Convert engine power from hp to kW.
How to convert Horsepower (hp) to Kilowatts (kW)?
Horsepower is often used for engines, while kilowatts are used in SI/metric systems. A common relationship is:
- 1 Horsepower (hp) ≈ 0.7457 Kilowatts (kW)
- 1 Kilowatt (kW) ≈ 1.34102 Horsepower (hp)
To convert Horsepower (hp) to Kilowatts (kW), multiply the value by 0.7457.
Formula: Kilowatts (kW) = Horsepower (hp) × 0.7457
Step-by-Step Calculation
- 1Take the number of Horsepower (hp) you want to convert (e.g., 100).
- 2Multiply that value by 0.7457.
- 3The result is the value in Kilowatts (kW). (Example: 100 × 0.7457 = 74.57 kW).
