About these units
Horsepower (Mechanical)
The mechanical horsepower (33,000 ft·lbf/min = 745.699 W) was defined by James Watt in the late 18th century to market his steam engine against horse-powered mills.
Kilowatt
The kilowatt is the SI power unit, standard for electric motors, power grids, and international engineering. As electric vehicles and motors replace combustion engines globally, kW increasingly displaces hp in technical specifications.
