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).
