  1. 1 hp = 745699871.582 µW
  2. 1 × 745699871.582 = 745699871.582 µW

How to convert horsepower to microwatts

1 hp = 745,699,871.582 µW, so multiply by 745,699,871.582 to go from horsepower (mechanical, 550 ft·lbf/s) to microwatts. Going the other way, 1 µW = 1.3410220896 × 10⁻⁹ hp.

µW = hp × 745,699,871.582
hp = µW × 1.3410220896

Worked example:

1 hp = 745699871.582 µW
5 × 745699871.582 = 3728499357.91 µW
