VA to hp Conversion Formula:

Real power P(HP) can be converted by calculating 1.34 times of apparent power S(VA) in Volt-Amp and power divided by 1000.

P(HP) = 1.34 x S(VA) x pf / 1000

The real power in horsepower = 0.00134 x apparent power in VA x power factor


What is the HP rating of the 2750 VA three-phase induction motor at 0.8 power factor?

HP = 1.34 x 2750 x 0.8 / 1000

Horsepower = 2.95 HP, approximately 3 HP.

Hence 2750 Volt-amp motor can be rated as 3 HP at 0.8 power factor.
