VA to hp Conversion Calculator:
Enter the VA rating and power factor to calculate horsepower rating.
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
Example:
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.
