About the units
Horsepower (hp)
550 foot-pounds per second, about 745.7 W. US car and motor ratings use mechanical horsepower. One horsepower equals 745.6998716 watts (W).
Megawatt (MW)
One million watts; used for power plants and wind turbines (a modern onshore turbine is 3–6 MW). One megawatt equals 1,000,000 watts (W).
