5 HP = 3.728499358 kW
Calculation working
- Result = input × source factor ÷ target factor
- 5 × 745.69987158227 ÷ 1,000 = 3.72849935791135 kW
- Factors refer to the same base quantity. Rounding is applied to the display, not intermediate calculations.
Display: 10 significant digits. More digits do not make the original measurement more accurate.

Using this power converter
Compare motor, inverter and equipment power ratings in watts, kilowatts, megawatts or mechanical horsepower.
Power is a rate of energy transfer. Horsepower here means mechanical horsepower, defined using 550 foot-pound-force per second.
Check before using the result
- Motor output power is not electrical input power. Efficiency and, for AC apparent power, power factor are separate inputs.
- Mechanical HP differs from metric PS and some electrical horsepower conventions. Confirm the datasheet convention.
Definitions and method: NIST: unit conversion factors and rounding. Calculations use double-precision arithmetic; the display precision can be adjusted above.
