kW ↔ PS Rechner
Use this quick converter for engine power in Kilowatt (kW) and Pferdestärke (PS).
Formula: 1 kW = 1.35962 PS | 1 PS = 0.73550 kW
What is a “kW Rechner in PS”?
A kW Rechner in PS is a power conversion tool that helps you translate between two common power units: kilowatt (kW) and Pferdestärke (PS) (metric horsepower). In many countries, technical documents use kW, while car ads and conversations often still use PS.
If you buy a car, compare engine options, or read registration papers, this conversion makes specs easier to understand quickly. For example, a compact car with 85 kW sounds more intuitive to many drivers when shown as approximately 116 PS.
kW to PS conversion formula
Standard equation
To convert from kilowatts to metric horsepower:
PS = kW × 1.35962
To convert from metric horsepower to kilowatts:
kW = PS × 0.73550
Quick examples
- 50 kW ≈ 67.98 PS
- 75 kW ≈ 101.97 PS
- 100 kW ≈ 135.96 PS
- 150 PS ≈ 110.33 kW
- 200 PS ≈ 147.10 kW
Why both units are still used
Power measurement has historical and regulatory roots. Engineers and international standards favor kW because it belongs to the SI system. However, PS remains culturally popular in automotive markets, especially in Europe, because it is familiar and easy to compare in casual conversation.
- kW: official technical and legal documentation
- PS: marketing, sales listings, enthusiast discussions
- Both together: better transparency for buyers
Practical use cases
1) Buying a used car
Listings may show PS, while paperwork shows kW. A fast converter avoids confusion and lets you compare vehicles accurately.
2) Import/export and registration
Different regions format vehicle data differently. Converting correctly helps with compliance and documentation checks.
3) Tuning and performance comparison
If tuning software outputs kW and forums discuss PS, you can align numbers and evaluate gains consistently.
Common mistakes to avoid
- Confusing PS with HP (mechanical horsepower); they are close but not identical.
- Rounding too aggressively when comparing similar models.
- Mixing wheel power and engine power values without context.
Final thoughts
A reliable kw rechner in ps saves time and prevents errors whenever you work with engine specifications. Use the calculator above to convert instantly in either direction, and keep the core factors in mind: 1 kW = 1.35962 PS and 1 PS = 0.73550 kW.
Whether you are comparing cars, reading a spec sheet, or preparing official forms, understanding these units gives you clearer and more confident decisions.
