About Kilowatt (kW)
A metric unit of power equal to 1,000 watts. Kilowatts are the practical unit for larger appliances and systems — electric kettles (1.5–3 kW), car EV motors (150–400 kW peak), home solar systems (5–10 kW), data centers, and industrial machinery. Utility-scale electricity is priced in kWh (kilowatt-hours), so the kilowatt is the natural rate unit for billing. Converting kW to horsepower (×1.341) is routine for internationally traded engines and motors.
About Horsepower (hp)
An imperial unit of power equal to approximately 745.7 watts, originally defined by James Watt to compare steam-engine output to draft horses pulling coal. Horsepower remains the dominant US unit for car engines, outboard motors, tractors, lawn equipment, and HVAC blowers. A typical sedan has 150–300 hp; a Tesla Model S Plaid has ~1,000 hp. Metric horsepower (PS, CV) is slightly different at 735.5 W — a detail that matters when comparing US-spec vs European-spec engine ratings.
