About power units
Power is the rate of using energy — energy divided by time. The watt (one joule per second) is the SI unit; kilowatts and megawatts scale it up. Engines are often rated in horsepower: mechanical horsepower is about 745.7 watts, while metric horsepower (PS, used in Europe and Japan) is about 735.5 watts, so the two differ slightly.
A useful anchor: one kilowatt is about 1.34 mechanical horsepower.
