Kilowatts (kW) to Horsepower (hp) Conversion
Kilowatts
The kilowatt (kW) is a unit of power equal to exactly 1,000 watts and is the practical unit for household appliances, vehicle engines, and small industrial machinery. Electric kettles typically consume 2–3 kW; domestic air conditioners run at 1–5 kW; EV charging stations provide 7–22 kW for home use. Engine power in electric vehicles is specified in kilowatts globally, replacing the horsepower in official EU vehicle type approval documentation.
Horsepower
Horsepower (hp) is a unit of power originally defined by James Watt in the 1780s to market steam engines against the work output of draft horses. The US mechanical horsepower equals exactly 745.69987158 watts. Multiple definitions exist: mechanical hp (745.7 W), metric hp (735.5 W), and electrical hp (746 W). In the automotive industry, engine power is expressed in horsepower in the US and UK markets, where 1 hp ≈ 0.7457 kW.
