About this converter
The kilowatt (kW) is a metric SI power unit equal to 1000 watts, while mechanical horsepower (hp) is a power unit equal to 745.699872 watts. One kilowatt equals 1.34102 mechanical horsepower, and one mechanical horsepower equals 0.7457 kW.
This converter includes mechanical horsepower, metric horsepower (PS), watts, and megawatts for vehicle, motor, pump, and generator comparisons. Mechanics, equipment buyers, electrical engineers, and automotive reviewers use kW and horsepower conversion when specifications come from different countries or standards.

How to Convert Kilowatts to Horsepower
Kilowatts to mechanical horsepower
For example, 110 kW x 1.34102 = 147.512 hp.
Mechanical horsepower to kilowatts
For example, 200 hp x 0.7457 = 149.14 kW.
When You Need to Convert Kilowatts to Horsepower
Vehicle specifications often list power differently by market. A 150 kW electric motor is 201.153 mechanical hp, which helps compare an EV rating with a gasoline engine listing.
Industrial motor and pump documents may use kilowatts on nameplates but horsepower in maintenance schedules. A 7.5 kW motor is 10.0577 hp, close to the common 10 hp class used in many catalogs.
Generator and compressor comparisons also need consistent units. A 50 kW generator is 67.0511 hp mechanically, but real engine sizing still needs efficiency, duty cycle, and safety margin checks.
