What is the formula to convert kVA to HP?

kVA to hp Conversion Formula:

KVA (kilo volt-amp) is the unit of apparent power and Hp is the unit of real power. Real power P(HP) is equal to the 1.34 times of apparent power S(kVA) in kVA and power factor. Hence for converting kVA to HP, P(HP) = 1.34 x S(kVA) x pf.
