How to convert VA to kW

How to convert apparent power in volt-amps (VA) to real power in kilowatts (kW).

Volt-amps to kW calculation formula

The real power P in kilowatts (kW) is equal to the apparent power S in volt-amps (VA), times the power factor PF divided by 1000:

P(kW) =  S(VA) × PF / 1000

 

So kilowatts are equal to volt-amps times the power factor divided by 1000.

kilowatts = volt-amps × PF / 1000

or

kW = VA × PF / 1000

Example

What is the real power in kilowatts when the apparent power is 3000 VA and the power factor is 0.8?

Solution:

P = 3000VA × 0.8 / 1000 = 2.4kW
