Gaugewise / HP to kW
Power & Torque
Convert engine power between HP and kW, and torque between Nm and lb-ft — built for comparing US and European spec sheets side by side.
| HP | kW | Metric PS |
|---|---|---|
| 150 | 111.9 | 152.1 |
| 200 | 149.1 | 202.8 |
| 300 | 223.7 | 304.2 |
| 400 | 298.3 | 405.6 |
| 500 | 372.8 | 507.0 |
How do I convert horsepower to kW?
Multiply horsepower by 0.745699872. To go from kW back to HP, divide by the same number.
How do I convert Nm to lb-ft?
Multiply Nm by 0.737562 to get lb-ft, or divide lb-ft by 0.737562 to get Nm.
Why do US and European car specs use different power units?
US listings typically use horsepower (hp); European listings typically use kilowatts (kW) or metric horsepower (PS) — a slightly different unit from mechanical horsepower. That's why comparing a US and European spec sheet directly can be misleading without converting to one common unit first.
