How to convert kVA to Watts

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

kVA to watts calculation formula

The real power P in watts (W) is equal to 1000 times the apparent power S in kilovolt-amps (kVA), times the power factor PF:

P(W) = 1000 × S(kVA) × PF

So watts are equal to 1000 times kilovolt-amps times the power factor.

watts = 1000 × kilovolt-amps × PF

or

W = 1000 × kVA × PF

Example

What is the real power in watts when the apparent power is 3 kVA and the power factor is 0.8?

Solution:

P = 1000 × 3kVA × 0.8 = 2400W
