How to convert watts to kVA
Watts to kVA calculation formula
The apparent power S in kilovolt-amps (kVA) is equal to the real power P in watts (W), divided by 1000 times the power factor PF:
S(kVA) = P(W) / (1000 × PF)
So kilovolt-amps are equal to watts divided by 1000 times the power factor.
kilovolt-amps = watts / (1000 × PF)
kVA = kW / (1000 × PF)
What is the apparent power in kilovolt-amps when the real power is 3000W and the power factor is 0.8?
S = 3000W / (1000 × 0.8) = 3.75kVA
