Watt
1 W = 0.001 kW = 0.00134 hp = 3.412 BTU/hr
Kilowatt
1 kW = 1000 W = 1.341 hp = 3412 BTU/hr
Horsepower
1 hp = 745.7 W = 0.7457 kW = 2544 BTU/hr
Metric Horsepower (PS)
1 PS = 735.5 W = 0.7355 kW
Our free power converter supports instant conversion between all common power units — watts, kilowatts, megawatts, milliwatts, horsepower, metric horsepower, BTU per hour, calories per second, joules per second and kilojoules per second. All calculations run in your browser — no data is sent to any server.
Our converter uses precise conversion factors based on international standards (SI). Results are accurate to 10 decimal places.
Yes! You can convert between any two power units — watts to horsepower, kilowatts to BTU/hr, metric horsepower to calories per second, or any other combination.
Horsepower (hp, also called imperial horsepower) is defined as 745.699872 watts. Metric horsepower (PS, Pferdestärke) is defined as 735.49875 watts. They are slightly different — 1 hp ≈ 1.0139 PS.
Absolutely. All conversions happen entirely in your browser. No data is ever sent to our servers or stored.
