How to Convert Megawatts to Horsepower (MW to hp)
Power conversions help compare car engines in hp and kW, and air-con units rated in BTU/h against their electrical draw in watts. This guide shows how to convert megawatts into horsepower by hand, with examples and a quick-reference table.
The conversion
To convert megawatts to horsepower, multiply the value by 1,341.0220888438. To go the other way, divide by the same number (or multiply by 0.0007456999). For a quick estimate, multiply by about 1,300.
Horsepower = megawatts × 1,341.0220888438
Worked examples
- 3 MW = 4,023.07 hp
- 12.5 MW = 16,762.78 hp
- 75 MW = 100,576.66 hp

Mistakes to avoid
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Background
Singapore adopted the metric system in the 1970s, replacing imperial units and traditional Chinese measures in most official uses. Metric units are now standard in schools, trade and government, but older units survive in property, markets and imported goods.
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
