Convert power between horsepower and kilowatts either way.
One imperial horsepower equals about 0.7457 kilowatts, so each side of the conversion is a fixed scaling of the other. Metric horsepower is a separate, slightly smaller unit. Brands quote power in hp, kW or PS depending on market, and mixing them up inflates or deflates a car's real output.
