kW ↔ PS Rechner
Convert quickly between Kilowatt (kW) and Pferdestärke (PS).
What is a kW PS Rechner?
A kW PS Rechner is a power conversion calculator used to translate engine output between two common units:
- kW (Kilowatt) — the SI unit of power used in most official technical documentation.
- PS (Pferdestärke) — a traditional metric horsepower unit widely used in automotive contexts across German-speaking countries.
If you compare vehicle specs from different regions, browse used-car listings, or read old and new documents side by side, this conversion is essential.
kW to PS formula and PS to kW formula
The conversion factors are straightforward and reliable for everyday use.
kW = PS × 0.73549875
Example: If a car is rated at 100 kW, then it has approximately 135.96 PS.
Example: If a vehicle is rated at 150 PS, then it has approximately 110.32 kW.
Why both units still matter
1) Legal and technical paperwork
Registration papers and modern technical data sheets often use kW. But sales listings, marketing materials, and enthusiast discussions may still highlight PS.
2) Comparing vehicles internationally
Some countries emphasize horsepower-style values while others use kW almost exclusively. Converting avoids confusion and makes comparisons fair.
3) Reading older sources
Classic car manuals and historical documentation frequently reference PS. New EV and hybrid specs are often primarily shown in kW.
Quick reference table
- 50 kW ≈ 67.98 PS
- 75 kW ≈ 101.97 PS
- 100 kW ≈ 135.96 PS
- 150 kW ≈ 203.94 PS
- 200 kW ≈ 271.92 PS
Common mistakes when converting
- Mixing up PS and mechanical hp (they are close, but not identical).
- Rounding too early in multi-step calculations.
- Comparing peak power numbers from different test standards without context.
Final tip
Use kW for precision and official consistency, and use PS when you want a familiar automotive reference. With this kW-PS converter, you can move between both instantly and confidently.
