Convert Horsepower (mechanical) to Milliwatts

Horsepower (mechanical) → Milliwatts
hp × 745699.9 = mW mW × 0.000001341022 = hp

To convert horsepower (mechanical) (hp) to milliwatts (mW), multiply the horsepower (mechanical) value by 745699.9. 1 hp = 745699.9 mW, and 1 mW = 0.000001341022 hp. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert mW to hp.
