kW to VA Conversion Calculator Online With Motor Chart
What Is A Kilowatt?
A kilowatt is a unit of energy that carries a lot of significance in everyday life — it’s the base unit used in the routine measurement for electrical energy. All the appliances and gadgets in your home consume electricity measured in kilowatts.
What is meant by volt-ampere?
Volt-ampere (VA) is a measurement of power in a direct current ( DC ) electrical circuit. The VA specification is also used in alternating current ( AC ) circuits, but it is less precise in this application, because it represents apparent power , which often differs from true power

Kilowatts to volt-amps calculation formula
The apparent power S in volt-amps (VA) is equal to 1000 times the real power P in kilowatts (kW), divided by the power factor PF
S(VA) = 1000 × P(kW)/ PF
So volt-amps are equal to 1000 times kilowatts divided by the power factor.
volt-amps = 1000 × kilowatts / PF
or
VA = 1000 × kW / PF
Example
What is the apparent power in volt-amps when the real power is 3 kW and the power factor is 0.8?
Solution:
S = 1000 × 3kW / 0.8 = 3750VA
