What is kW (kW)?
The kilowatt (kW) equals 1,000 watts. It is the legal unit for engine power in the EU and rates appliances, motors and electric-car charging speeds.
What is W (W)?
The watt (W) is the SI unit of power: one joule per second. It measures the rate of energy use — a phone charger draws a few watts, an electric kettle around 2,000 W.
Why convert kW to W?
Car engines are rated in kilowatts by EU law, but everyday talk uses horsepower — PS in Europe, hp in the US and UK. Converting between kW, PS and hp is a constant need when comparing cars.
One metric horsepower (PS) is defined as exactly 735.49875 W, so 1 kW = 1.3596 PS. Mechanical horsepower (hp) is 745.7 W, giving 1 kW = 1.341 hp — the two horsepowers differ by about 1.4%.
