The power converter translates values between watt (W), kilowatt (kW), megawatt (MW), horsepower (hp, metric = 735.5 W), and BTU/h. Type a number into any field and the other units update instantly.
Converting power is handy when comparing car and equipment specs (horsepower versus kilowatts), in energy calculations, and when choosing climate equipment (air conditioner capacity is often listed in BTU/h). Reference points: 1 kW ≈ 1.36 hp, 1 hp = 735.5 W, 1 kW ≈ 3,412 BTU/h. For example, a 150 hp engine is roughly 110 kW.
Calculations go through the watt as a base unit, so any pair converts precisely. Everything runs right in your browser, with no data sent anywhere.
