About Horsepower (mechanical)
Mechanical horsepower here is the US definition: 550 ft·lbf/s ≈ 745.70 W. Automotive and industrial specs often cite hp.
About Megawatt
One megawatt is one million watts. Utility generation, large drives, and grid studies use MW.
How to convert horsepower (mechanical, 550 ft·lb/s) to megawatts
1 horsepower (mechanical) is equal to 0.00074569987158 megawatt when both are expressed in watt-equivalents:
1 hp = (745.6998715822702 W ÷ 1,000,000 W) megaw = 0.00074569987158 megaw
Each horsepower (mechanical) is defined as 745.6998715822702 W and each megawatt as 1,000,000 W in this tool, so one hp equals 745.6998715822702 ÷ 1,000,000 megaw = 0.00074569987158 megaw.
Let d(hp) be the numeric value in Horsepower (mechanical) (hp), and d(megaw) the value in Megawatt (megaw). Then:
d(megaw) = d(hp) × (745.6998715822702 / 1,000,000)
Equivalently, divide by how many hp fit into one megaw (watts per megaw divided by watts per hp):
d(megaw) = d(hp) ÷ 1341.02208959502786
Or: megawatt = horsepower (mechanical) ÷ 1341.02208959502786
Examples
Example #1: Convert 1 hp to megawatt
1 hp = 1 hp × (745.6998715822702/1,000,000) megaw = 0.0007456999 megaw
1 hp = 1 hp ÷ 1341.02208959502786 = 0.0007456999 megaw
Intermediate watts: 745.699871582 W
Example #2: Convert 10 hp to megawatt
10 hp = 10 hp × (745.6998715822702/1,000,000) megaw = 0.0074569987 megaw
10 hp = 10 hp ÷ 1341.02208959502786 = 0.0074569987 megaw
Intermediate watts: 7,456.99871582 W
Summary
To convert Horsepower (mechanical) to Megawatt, multiply the value in hp by the ratio of watts per hp divided by watts per megaw. Equivalently: value_megaw = value_hp × (745.6998715822702 / 1000000). Numerically, 1 hp equals 0.0007456998715822703 megaw.
Relationship context
