Horsepower to Megawatts Converter

To convert a measurement in horsepower to megawatts, multiply the value by 0.000745699872. The conversion factor comes from the relationship between both units and the watt.

For example, to convert 5 hp to megawatts: 5 × 0.000745699872 = 0.003728499358 MW.

Mechanical horsepower (hp) is a unit of power equal to about 745.7 watts, originally defined to compare engine output to the work of draft horses. James Watt coined horsepower in the 1780s to market his steam engines against the horses they replaced. Mechanical horsepower remains the dominant unit for engine power in the United States.

Common uses of horsepower include: Car and motorcycle engine ratings (US); Lawn mowers and power tools; Marine and outboard motors; Comparing engine performance.

A megawatt equals one million watts and is used to rate large-scale power generation and industrial equipment. The megawatt became the standard scale for describing power stations and grid capacity as electricity generation industrialized. A single large wind turbine produces several megawatts.

Common uses of megawatts include: Power plant and grid capacity; Wind turbine and solar farm output; Industrial machinery and data centers; Utility-scale energy planning.

Here are some common values converted:

1 hp = 0.000745699872 MW 5 hp = 0.003728499358 MW 10 hp = 0.007456998716 MW 50 hp = 0.037284993579 MW 100 hp = 0.074569987158 MW
