## What is horsepower (electric)?

The **electrical horsepower** is a unit of power equal to 746 watts (1 hp = 746 W), the derived unit of power in the International System of Units (SI). It is also equal to 0.746 kilowatts (kW), or 7.46x10-4 megawatts (MW), or 7.46x10-7 gigawatts (GW), or 2,545.4576598 British thermal units (IT) per hour (BTU/h), or 641.873806 kilocalories (thermochemical) per hour (kcal/h) or 1.014 horsepower (metric) (hp).

The **horsepower definition** varies as follows:

- The mechanical horsepower or Imperial horsepower (hp) is equal to 745.699872 watts (W)
- The electrical horsepower (hp) is equal to 746 watts (W)
- The hydraulic horsepower (hp) is equal to 745.699872 watts (W)
- The metric horsepower (hp) is equal to 735.49875 watts (W)
- The boiler horsepower or steam horsepower (hp) is equal to 9,810.657 watts (W)

The electrical horsepower is used for rating electric motors.
