HP to kW Converter
Horsepower to kilowatts — mechanical, metric, or electrical HP.
Most car manufacturers outside the US quote metric HP (PS or CV). A car rated 200 PS is ~197 mechanical HP. The difference is under 2% — small but not zero.
| Unit | Value |
|---|---|
| Kilowatts (kW) | 149.14 kW |
| Mechanical HP | 200 HP |
| Metric HP (PS / CV) | 202.774 PS |
| Watts | 149,140 W |

FAQ
- How do I convert HP to kW?
- Multiply HP by 0.7457 (for mechanical/US HP). 200 HP × 0.7457 ≈ 149.1 kW.
- Is metric HP (PS/CV) the same as US HP?
- No. Metric HP (also called PS or CV) is 735.5 W, versus 745.7 W for mechanical HP. European cars usually quote metric HP; US cars mechanical HP. Difference: ~1.4%.
- What is bhp?
- Brake horsepower — HP measured at the crankshaft with a brake dynamometer. In practice, bhp = mechanical HP for spec sheets.
