Convert watts (W), kilowatts (kW), horsepower (hp), and metric horsepower (PS). Power (P) is the rate of energy transfer: P = E/t. The watt (W) is the SI unit (1 W = 1 J/s).
This power converter transforms values from Watts (W) to Horsepower (hp). Results update instantly using the exact conversion factor.
The watt (W) is the SI unit of power (1 W = 1 J/s).
Horsepower (hp) is an imperial power unit; 1 hp ≈ 745.7 W.
1 W ÷ 745.699872 = 0.001341 hp
hp = W ÷ 745.699872
To convert W to hp, divide the value in W by 745.699872 (since 1 W = 0.001341 hp). Equivalently, multiply by 0.001341. Example: 1 W = 1 W × 0.001341 = 0.001341 hp.
10 W = 0.01341 hp ÷ 745.699872 = 10 W
