Power Converter
Power across watts, horsepower and BTU per hour. Mechanical horsepower and metric horsepower differ by about one and a half percent, which is why the same engine is quoted differently in different markets.
Also called: kw to hp, horsepower converter, watts to btu.
Result
1.341022
1 Kilowatt is 1.341022 Horsepower (mechanical). The factor is 1.3410220896, and the inverse is 0.7456998716. The table below gives the same value in every power unit at once.

Method and background
How this is calculated
Power is energy per unit time and everything is held against the watt. Two horsepowers are in common use: the mechanical one, defined as 550 foot pounds per second, and the metric PS, defined as 75 kilogram force metres per second. They are close enough to be confused and far enough apart to matter on a spec sheet.

Worked examples
Each of these is asserted on every build. If a change to the engine ever moved one of these answers, the build would fail before the page could print it.
