How to convert watts to kVA

How to convert real power in watts (W) to apparent power in kilovolt-amps (kVA).

Watts to kVA calculation formula

So 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)

or

kVA = W / (1000 × PF)

Example 1

What is the apparent power in kilovolt-amps when the real power is 2000W and the power factor is 0.8?

Solution:

S = 2000W / (1000 × 0.8) = 2.5kVA

Example 2

What is the apparent power in kilovolt-amps when the real power is 4000W and the power factor is 0.8?

Solution:

S = 4000W / (1000 × 0.8) = 5kVA

Example 3

What is the apparent power in kilovolt-amps when the real power is 5000W and the power factor is 0.8?

Solution:

S = 5000W / (1000 × 0.8) = 6.25kVA
