Horsepower to Kilowatts Converter

Convert horsepower to kilowatts quickly for motor sizing, power rating analysis, electrical engineering calculations, and industrial machinery specifications using accurate conversion factors.

What Is Horsepower?

Horsepower is a unit of power measurement that represents the rate of mechanical work. Engineers use horsepower to describe engine power, motor output, compressor performance, pump capacity, and industrial machinery ratings. Common types include mechanical horsepower, metric horsepower, and brake horsepower.

What Is a Kilowatt?

A kilowatt (kW) is an SI unit of power equal to 1,000 watts. Electrical engineering, IEC standards, industrial automation, generators, electric motors, and HVAC equipment commonly use kilowatts to express power output, energy transfer capacity, and equipment performance ratings.

HP to kW Formula

Use the standard power conversion factor to convert horsepower into kilowatts for motors, engines, generators, pumps, and industrial equipment.

kW=HP×0.745699872 kW = HP \times 0.745699872

Practical Example Horsepower to Kilowatt Conversions

Example:

10 HP×0.745699872=7.46 kW 10\ HP \times 0.745699872 = 7.46\ kW

A 10 horsepower motor produces approximately 7.46 kilowatts of power.
