Enter a power in kilowatts to see mechanical horsepower. Typical when a motor is labelled in kW and you want an hp figure.

How it works

Because 1 mechanical horsepower is 0.7456998715822702 kW, converting back is division: hp = kW ÷ 0.7456998716. 75 kW is about 100.58 hp. Electric-vehicle peak power is often advertised in kW; this conversion does not add drivetrain losses or peak-versus-continuous ratings.

Formula

hp = kW ÷ 0.7456998715822702

Worked examples

  • 75 kW 100.5778 hp
  • 1 kW 1.3410 hp

Useful notes

  • Mechanical horsepower, the inverse of the HP to kW page.
  • Nameplate kW is not the same as energy used (kWh).

FAQ

How many horsepower is 1 kW?
About 1.341 mechanical horsepower (1 ÷ 0.7457).
Why doesn’t 74.57 kW show as 100 hp exactly in the display?
It should, within rounding. 100 × 0.7456998716 = 74.569987… kW. Entering a rounded 74.57 will be a hair off 100.
Can I use this for metric horsepower?
Not accurately. PS uses 735.49875 W. This page is mechanical hp only.
