One horsepower is approximately equal to how many kilowatts?

Explanation:
Converting horsepower to kilowatts uses the watt as the base unit. One mechanical horsepower is defined as 745.7 watts. Since a kilowatt is 1000 watts, one horsepower equals 745.7/1000 = 0.7457 kilowatts. The best match is 0.7457 kilowatt, which is the precise conversion. The other options are noticeably farther from this value. For quick use, you can remember 1 hp ≈ 0.746 kW.
