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. One horsepower (mechanical) equals 745699.9 milliwatts; one milliwatts equals 0.000001341022 horsepower (mechanical). The conversion is a linear scaling with no offset, so the same factor applies to any value.
