1Hp = 0.746 kW 

Hp= Horsepower, kW = Kilowatt

VA = VxI

Watt = VICosφ

VAR = VISinφ

Single Phase:
kVA = VxI,  kW = VxIxPF, I = kWx1000/VxPF,  V = kWx1000/IxPF

Three Phase:
kVA =3x VxI/1000,  kW =  3xVxIxPF/1000,  (P = 1.732VICosφ)

VL = 3xVP ,  VP = VL, /3,  IL = IP  (Star Connection)

IL = 3xIP,     IP = IL /√3,   VL =VP  (Delta Connection)
