Megawatt to Horsepower (Mechanical) Formula & Unit Definitions
The conversion ratio derives from dividing 1,000,000 watts by 745.69987158227022 watts per horsepower, yielding approximately 1,341.0220888 mechanical horsepower per megawatt. To convert megawatts to mechanical horsepower, multiply the megawatt figure by 1,341.022 (or divide by 0.0007456999). To perform the reverse conversion from horsepower to megawatts, multiply horsepower by 0.0007456999 (or divide by 1,341.022).
Quick Estimation: Multiply megawatts by 1,340 (or multiply MW by 4,000 and divide by 3). For example, 1 MW × 1,340 = 1,340 hp (exact: 1,341.02 hp); 3 MW × 1,340 = 4,020 hp (exact: 4,023.07 hp); 10 MW × 1,340 = 13,400 hp (exact: 13,410.22 hp).
Megawatt Standard (MW)
