Lets you determine the amperage or the KVA according to the parameters that are known. You must choose the number of phases and give at least two (2) of the three (3) parameters of the equation to get a result.

How to convert real power in kilowatts (kW) to apparent power in kilovolt-amps (kVA).

kW to kVA calculation formula

The apparent power S in kilovolt-amps (kVA) is equal to the real power P in kilowatts (kW), divided by the Power Factor PF:

S_(kVA) =  P_(kW) / PF

So kilovolt-amps are equal to kilowatts divided by the power factor.

kilovolt-amps = kilowatts / PF

or

kVA = kW / PF

Example

What is the apparent power in kilovolt-amps when the real power is 3 kW and the power factor is 0.8?

Solution:

S = 3kW / 0.8 = 3.75kVA
