1 Horsepower (metric) = 0.7355 Kilowatt
Key Formulas
Kilowatt → Horsepower (mech)
hp = kW × 1.34102Horsepower (mech) → Kilowatt
kW = hp × 0.7457Watt → Kilowatt
kW = W × 0.001Kilowatt → Watt
W = kW × 1000Formula
kW = PS × 0.735499EU regulations require vehicle power to be declared in kilowatts for type approval, and many EU countries use kW for vehicle tax and insurance calculation. European car enthusiasts also use this conversion to compare their PS-rated cars to global kW benchmarks. A 250 PS sports car = 183.9 kW, which directly appears on the vehicle's Certificate of Conformity for EU registration.
