- 1 mW = 1.3410220896e-6 hp
- 1 × 1.3410220896e-6 = 1.3410220896e-6 hp
How to convert milliwatts to horsepower
1 mW = 1.3410220896 × 10⁻⁶ hp, so multiply by 1.3410220896 to go from milliwatts to horsepower (mechanical, 550 ft·lbf/s). Going the other way, 1 hp = 745,699.871582 mW.
hp = mW × 1.3410220896 mW = hp × 745,699.871582
Worked example:
1 mW = 1.3410220896e-6 hp 5 × 1.3410220896e-6 = 6.70511044798e-6 hp
