kW to HP Converter
Convert kilowatts to horsepower instantly — 1 kW = 1.341 hp, so 100 kW = 134.1 hp. Great for EV and engine specs. Converts both ways.
About the kW to HP Converter
This free kW to HP converter divides kilowatts by 0.7457 to give mechanical horsepower — 1 kW is about 1.341 hp. Edit either field and the other updates instantly.
Kilowatt ratings appear on electric vehicle spec sheets, vehicle registration documents in many countries, generator nameplates and industrial motors, but most people still think in horsepower. Converting tells you a 150 kW EV motor delivers about 201 hp, a Suzuki Alto's 48 kW is roughly 64 hp, and a 5 kVA generator around 4 kW output is 5.4 hp of usable power.
For European brochure figures in PS (metric horsepower), divide kW by 0.7355 instead — the note under the result explains the small difference.

Frequently Asked Questions
How many hp is 100 kW?
100 kW equals 134.1 mechanical horsepower (or 136.0 metric PS). Other quick values: 50 kW = 67.1 hp, 75 kW = 100.6 hp, 200 kW = 268.2 hp and 300 kW = 402.3 hp.
What is the kW to hp formula?
hp = kW ÷ 0.7457, or equivalently kW × 1.34102, for mechanical horsepower. For metric horsepower (PS), hp(PS) = kW ÷ 0.7355 = kW × 1.35962.
How much horsepower does a 150 kW electric car have?
150 kW equals about 201 hp. Typical EV motors: 100 kW ≈ 134 hp (compact EVs), 150 kW ≈ 201 hp (mid-size), 250 kW ≈ 335 hp (performance models). Dual-motor EVs add the two ratings together.
Why do some countries rate cars in kW instead of hp?
The kilowatt is the SI unit of power, so registration papers, insurance categories and official specs in Australia, South Africa and much of Europe use kW. Horsepower survives mainly in marketing. Multiply kW by 1.341 to translate.
How many hp is a 37 kW motor?
37 kW is 49.6 hp — which is why 37 kW industrial motors are sold as "50 hp" motors. Similarly, 7.5 kW ≈ 10 hp and 75 kW ≈ 100 hp; standard motor sizes were built around round hp numbers.
