How to Convert Megawatt to Horsepower
- 1 MW = 1341.02209 hp
- 1 hp = 0.0007456998716 MW
- Example: convert 15 MW to hp: 15 MW = 15 × 1341.02209 hp = 20115.33134 hp
Reference conditions. hp: Mechanical (imperial) horsepower, 550 ft·lbf/s. Metric horsepower (PS) is about 1.4 % smaller.
Formula
hp = MW × 1341.022089595
Derivation from SI units:
- 1 MW = 10⁶ W
- 1 hp = 550 ft·lbf/s = 745.69987158227 W
- 1 MW = 1000000 W ÷ 745.6998715823 W per hp = 1341.022089595 hp
Both units are defined exactly, so the factor is exact. Megawatt definition: megawatt; Horsepower definition: horsepower.
Worked examples
- A reading of 3 MW converts to 4023.066269 hp.
3 MW × 1341.02209 = 4023.066269 hp - A value of 50 MW is 67051.10448 hp.
50 MW × 1341.02209 = 67051.10448 hp
