How to use
- Type the power you want to convert.
- Choose the units to convert from and to. Use the swap button to flip them.
How it works
Every unit is converted through watts using exact definitions: a kilowatt is 1,000 W, a megawatt is a million W, mechanical horsepower is 550 foot-pounds of force per second (about 745.7 W), metric horsepower (PS) is 75 kilogram-force metres per second (735.49875 W), and a BTU per hour is a British thermal unit spread over an hour (about 0.293 W). So 100 kW is about 134.1 hp.
The watt comes from the BIPM SI Brochure; the horsepower and BTU definitions from NIST Special Publication 811.
Horsepower comes in several versions. This converter has the mechanical (imperial) horsepower and the metric one, which differ by about 1.4 %. Car makers outside the US usually quote metric.
