UnitConKilowatts to Horsepower Converter
Convert kilowatts to horsepower for comparing electric motors with combustion engines, understanding vehicle power ratings, and translating European car specs for US markets. European and Asian cars are rated in kW while US buyers expect horsepower.
Formula
Multiply kilowatts by 1.34102 to get mechanical horsepower. To reverse, divide horsepower by 1.34102 to get kilowatts.

About these units
Kilowatt
The kilowatt is the SI power unit, universally used in engineering and the standard for electric motor ratings in Europe and Asia.
Horsepower (Mechanical)
The horsepower was defined by James Watt as 33,000 foot-pounds per minute (745.7 W), roughly the sustained output of a strong horse. Despite being a non-SI unit, it remains the standard for engine power in the US automotive market.
