## Formula

- `1 kW = 1.35962 PS`
- `metric horsepower (PS) = kilowatts × 1.359621617`
- Reverse: `kilowatts = metric horsepower (PS) × 0.73549875`

The factor follows from the SI definitions of both units (NIST SP 811); values below are rounded to 6 significant figures, the API returns up to 12.

## Worked examples

- 5 kW = 6.79811 PS
- 12.5 kW = 16.9953 PS
- 100 kW = 135.962 PS

## FAQ

**How many metric horsepower (PS) are in one kilowatt?**

1 kW = 1.35962 PS. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

**What is the formula to convert kilowatts to metric horsepower (PS)?**

Multiply the value in kilowatts by 1.359621617: metric horsepower (PS) = kilowatts × 1.359621617. For example, 5 kW = 6.79811 PS.

**How do I convert metric horsepower (PS) back to kilowatts?**

Multiply by the inverse factor 0.73549875 (kilowatts = metric horsepower (PS) × 0.73549875), or use the metric horsepower (PS)-to-kilowatts page.
