Overview

About converting kilowatts to horsepower

Kilowatts to horsepower converts metric power figures — common on European car papers and electric motors — back into the horsepower drivers instinctively understand.

Since one mechanical horsepower is 0.7457 kW, one kilowatt is about 1.341 horsepower. To convert, multiply kilowatts by 1.341. So 100 kW is 134 hp, and a 70 kW city-car motor is about 94 hp.

This conversion matters most when comparing electric and combustion vehicles. An EV rated at 150 kW delivers roughly 201 hp — useful context when its specs sit next to a petrol car still advertised in horsepower.

Practical Tips

Quick estimate: multiply kilowatts by 1.34.
Anchor: 75 kW ≈ 100 hp.
