Convert between HP and kW instantly — bidirectional with vehicle & motor reference
Formulas:
kW = HP × 0.7457
HP = kW × 1.3410
1 HP = 745.7 W = 2,544.43 BTU/hr

1 Horsepower (HP) = 0.7457 Kilowatts (kW). Multiply HP by 0.7457 to get kW. For example, 100 HP = 74.57 kW. To convert back, multiply kW by 1.3410.
Both measure power output. Horsepower (HP) is commonly used in the US and UK for engines and motors. Kilowatts (kW) is the SI metric unit used internationally. Most countries outside the US list vehicle power in kW. 1 HP ≈ 0.7457 kW.
A typical sedan has 150-200 HP (112-149 kW). Sports cars range from 300-500 HP (224-373 kW). Electric vehicles often exceed 300 HP with instant torque delivery. Trucks and SUVs typically have 250-400 HP.
