kW to HP converter

Convert kilowatt [kW] to horsepower [hp], or vice versa.

From:kilowatt (kW)
To:horsepower (hp)

1 kilowatt (kW) = 1.3410 horsepower (hp)

1 horsepower = 0.74569987 kilowatts

FORMULA

HP = kW × 1.34102

For reverse: kW = HP × 0.7457. This uses mechanical horsepower (most common).

HOW TO CONVERT
  1. Enter kilowatts in the From field
  2. Click Convert — result appears in HP
  3. Use ⇅ to reverse (HP → kW)
IMPORTANT NOTE
Mechanical HP = 745.7 W (this converter)Metric HP (PS) = 735.5 WElectrical HP = 746 W

Kilowatt

Definition: A kilowatt (symbol: kW) is a unit of power equal to 1,000 watts. It is part of the International System of Units (SI). 1 kW = 1,000 J/s (joules per second).

Current use: The kilowatt is the standard unit of power in most countries for measuring engine output, electrical appliances, and industrial machinery. Electric vehicle motors, for example, are commonly rated in kW.

Horsepower

Definition: Horsepower (symbol: hp) is a unit of power with multiple definitions. Mechanical horsepower (used in this converter) = 550 foot-pounds per second = 745.69987 watts. It was originally defined by James Watt to compare the output of steam engines to draft horses.

Current use: Horsepower is primarily used in the United States and United Kingdom to rate the output of engines in cars, motorcycles, aircraft, and industrial equipment.
