Horsepower to Megawatts (hp to MW) Converter
1 horsepower (hp) = 0.0007457 megawatts (MW). To convert horsepower to megawatts, multiply by 0.0007457: 150 hp × 0.0007457 = 0.111855 MW.
Quick facts
- 1 hp = 0.0007457 MW
- 1 MW = 1,341.02 hp
- Formula: MW = hp × 0.0007457
- Quick estimate: multiply by about 0.00075
How to convert horsepower to megawatts
- Take the value in horsepower.
- Multiply it by 0.0007457 (the number of megawatts in one horsepower).
- Round the result to the precision you need.
Worked example (a family car engine): 150 hp × 0.0007457 = 0.111855 MW.
To convert megawatts back to horsepower, multiply by 1,341.02, or divide by 0.0007457.
