Convert between kilowatts (kW) and pferdestarke (PS) for engine power calculations in automotive, engineering, and mechanical applications.
Select conversion direction:
Kilowatt to Pferdestarke Conversion:
1 Kilowatt (kW) ≈ 1.3596 Pferdestarke (PS)
PS = kW × 1.3596216173 | kW = PS × 0.73549875 (e.g., 100 kW ≈ 135.96 PS; 150 PS ≈ 110.32 kW)

Understanding these power units used in automotive engineering, machinery, and energy applications.
| Unit | Definition | Conversion | Common Uses |
|---|---|---|---|
| Kilowatt (kW) | SI unit of power: 1 kW = 1000 watts = 1000 J/s | 1 kW ≈ 1.3596 PS 1 kW ≈ 1.3410 hp (imperial) |
Global standard for engine power, electric motors, power generation |
| Pferdestarke (PS) | Metric horsepower: 1 PS ≈ power to lift 75 kg at 1 m/s | 1 PS ≈ 0.7355 kW 1 PS ≈ 0.9863 hp (imperial) |
Vehicle engine power in Europe, particularly Germany, Austria, Switzerland |
*Note: Both units measure power - the rate at which work is done or energy is transferred.
1 pferdestarke is approximately 73.55% of a kilowatt, meaning 1 kW equals about 1.36 PS
The relationship between these power units is defined as:
1 PS = 75 kg·m/s (mechanical definition)
1 kW = 1000 W = 1000 J/s (SI definition)
1 PS ≈ 0.73549875 kW
1 kW ≈ 1.3596216173 PS
This conversion factor comes from the mechanical equivalence between the metric horsepower definition (lifting 75 kg at 1 m/s) and the joule-based definition of the watt.

Common questions about kilowatt to pferdestarke conversions
PS (Pferdestarke) and kW (kilowatt) are both units of power, but they have different origins and definitions:
The conversion factor is approximately 1 kW = 1.3596 PS or 1 PS = 0.7355 kW.
Pferdestarke remains in use primarily due to tradition and regional习惯:
However, kW is the internationally recognized SI unit and is increasingly used alongside PS in technical specifications, especially for electric vehicles and international markets.
There are several different definitions of "horsepower" used around the world:
1 Pferdestarke (PS) ≈ 0.9863 mechanical horsepower (hp, imperial)
1 mechanical horsepower (hp) ≈ 1.0139 PS
1 PS ≈ 0.7355 kW
1 mechanical horsepower ≈ 0.7457 kW
The key differences:
This conversion is particularly important in industries where power ratings are critical specifications:
