Converting kW to PS

Converting kilowatts (kW) to metric horsepower (PS) is an essential calculation for vehicle power evaluation. The conversion formula is: kW × 1.35962 = PS. This conversion factor is derived from the definition of 1 PS as 75 kilogram-force meters per second (75 kgf·m/s), which equals 735.49875 Watts (W).

Was bedeuten kW und PS?

Die beiden wichtigsten Maßeinheiten für Motorleistung verständlich erklärt

Offizielle SI-Einheit

Was ist ein Kilowatt (kW)?

Das Kilowatt (kW) ist die international genormte, gesetzliche Standardeinheit für Leistung (1 kW = 1.000 Watt). Es beschreibt die verrichtete physikalische Arbeit pro Zeiteinheit.

Metrische Pferdestärke (DIN 66036)

Was ist eine Pferdestärke (PS)?

Die Pferdestärke (PS) ist die historisch etablierte Maßeinheit für Fahrzeugleistung. 1 PS ist physikalisch definiert als die Kraft, die benötigt wird, um 75 Kilogramm in 1 Sekunde um 1 Meter anzuheben.

The complete kW-to-PS calculation workflow

Read the kW Rating

Find the engine power in kW from your vehicle registration document (Field P.2), specification sheet, or owner manual.

Multiply by 1.35962

Multiply the recorded kW value by the exact conversion factor 1.35962. The formula is: PS = kW × 1.35962.

Get Your PS Output

The result is the engine power in metric horsepower (PS). An engine rated at 100 kW delivers 100 × 1.35962 = 135.96 PS.

An electric vehicle motor with 150 kW produces 150 × 1.35962 = 203.94 PS. An internal combustion engine with 85 kW delivers 85 × 1.35962 = 115.57 PS. The exact same formula applies across combustion, electric, and hybrid drivetrains.

Frequently Asked Questions

11 in-depth answers on automotive power measurement

What does PS mean in automotive ratings?

PS stands for Pferdestärke (metric horsepower). 1 PS is defined as the power required to lift 75 kilograms by 1 meter in 1 second (75 kgf·m/s). In DIN 66036 standards, 1 PS equals 735.49875 Watts (0.73550 kW).

What does KW mean for engine output?

kW stands for Kilowatt and is the official SI standard unit for mechanical and electrical power. 1 kW equals 1,000 Watts. European Union regulations require kW as the primary unit in vehicle registration documents.

How do you convert kW to PS?

To convert kilowatts to metric horsepower, multiply the kW rating by 1.35962 (Formula: PS = kW × 1.35962). For example, 110 kW × 1.35962 = 149.56 PS.

How many PS is 1 kW?

1 kW equals exactly 1.35962 PS. This value is derived from dividing 1,000 W by 735.49875 W.

How many PS is 100 kW?

100 kW equals 135.96 PS (100 × 1.35962 = 135.96 PS), which equals approximately 134.10 mechanical horsepower (hp).

How many PS is 150 kW?

150 kW equals 203.94 PS (150 × 1.35962 = 203.94 PS). This is a typical rating for executive sedans and mid-range electric vehicles.

What conversion factor is used between kW and PS?

The standard metric conversion factor is 1.35962 for kW to PS, and 0.73550 for PS to kW.

Why do car manufacturers still advertise in PS?

PS has been established for over a century. Consumers find horsepower figures easier to understand and relate to, while higher numbers also provide psychological marketing advantages.

Where is the kW rating listed on vehicle documents?

In EU registration certificates (Part I), the power in kW is listed in Field P.2. It is also found in the vehicle handbook and the engine VIN plate.

Can decimal kW values be converted to PS?

Yes. The formula PS = kW × 1.35962 applies to all numbers, such as 0.75 kW = 1.02 PS or 132.5 kW = 180.15 PS.

How can I verify a converted horsepower calculation?

Divide the PS result by 1.35962 or multiply by 0.73550. The resulting value should match the original kW rating.
