kW to HP Conversion: Kilowatts to Horsepower Explained

Power is measured differently around the world. Europe and most countries use kilowatts (kW) while the US and UK commonly use horsepower (HP). Converting between them is essential when comparing car specifications, machinery, and electrical motors.

The Conversion Formulas

1 kW = 1.341 mechanical HP
1 kW = 1.360 metric HP (PS)
1 kW = 1.340 electrical HP

To convert kW to HP: multiply by 1.341
To convert HP to kW: divide by 1.341

Common Power Conversions

50 kW = 67 HP (typical small car)
75 kW = 101 HP (compact car)
100 kW = 134 HP (mid-size car)
150 kW = 201 HP (performance car)
200 kW = 268 HP (sports car)
300 kW = 402 HP (luxury performance)
1 MW (1000 kW) = 1341 HP (heavy machinery)

Different Types of Horsepower

Mechanical horsepower (HP) is the US standard, used for car engines. Metric horsepower (PS) is used in Europe — 1 PS = 0.986 HP. Electrical horsepower is used for motors. The differences are small but can matter in precise engineering. Use our power converter above for accurate results.

Why kW is the Global Standard

The kilowatt is the SI unit for power and is used globally in science, engineering, and electrical applications. While car enthusiasts may prefer horsepower, kW provides a universal standard that eliminates confusion between different HP definitions.
