- 1 hp = 745699.871582 mW
- 1 × 745699.871582 = 745699.871582 mW
How to convert horsepower to milliwatts
1 hp = 745,699.871582 mW, so multiply by 745,699.871582 to go from horsepower (mechanical, 550 ft·lbf/s) to milliwatts. Going the other way, 1 mW = 1.3410220896 × 10⁻⁶ hp.
mW = hp × 745,699.871582 hp = mW × 1.3410220896
Worked example:
1 hp = 745699.871582 mW 5 × 745699.871582 = 3728499.35791 mW
