About Megawatt
One megawatt is one million watts. Utility generation, large drives, and grid studies use MW.
About Horsepower (mechanical)
Mechanical horsepower here is the US definition: 550 ft·lbf/s ≈ 745.70 W. Automotive and industrial specs often cite hp.
How to convert megawatts to horsepower (mechanical, 550 ft·lb/s)
1 megawatt is equal to 1341.02208959502786 horsepower (mechanical) when both are expressed in watt-equivalents:
1 megaw = (1,000,000 W ÷ 745.6998715822702 W) hp = 1341.02208959502786 hp
Each megawatt is defined as 1,000,000 W and each horsepower (mechanical) as 745.6998715822702 W in this tool, so one megaw equals 1,000,000 ÷ 745.6998715822702 hp = 1341.02208959502786 hp.
Let d(megaw) be the numeric value in Megawatt (megaw), and d(hp) the value in Horsepower (mechanical) (hp). Then:
d(hp) = d(megaw) × (1,000,000 / 745.6998715822702)
Equivalently, divide by how many megaw fit into one hp (watts per hp divided by watts per megaw):
d(hp) = d(megaw) ÷ 0.00074569987158
Or: horsepower (mechanical) = megawatt ÷ 0.00074569987158
Examples
Example #1: Convert 1 megaw to horsepower (mechanical)
1 megaw = 1 megaw × (1,000,000/745.6998715822702) hp = 1341.0220896 hp
1 megaw = 1 megaw ÷ 0.00074569987158 = 1341.0220896 hp
Intermediate watts: 1,000,000 W
Example #2: Convert 10 megaw to horsepower (mechanical)
10 megaw = 10 megaw × (1,000,000/745.6998715822702) hp = 13410.220896 hp
10 megaw = 10 megaw ÷ 0.00074569987158 = 13410.220896 hp
Intermediate watts: 10,000,000 W
Summary
To convert Megawatt to Horsepower (mechanical), multiply the value in megaw by the ratio of watts per megaw divided by watts per hp. Equivalently: value_hp = value_megaw × (1000000 / 745.6998715822702). Numerically, 1 megaw equals 1341.0220895950279 hp.
Relationship context
You are converting between SI / decimal power (watts and prefixes) (Megawatts) and mechanical power (horsepower, ft·lb/s) (Horsepower (mechanical, 550 ft·lb/s)). All linear values are mapped through watts first. The numeric factor is 1.341022e+3.
