Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.
Conversion Using the Power Formula :
AC Single Phase KW to VA Calculation:
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:
For example, let’s Convert the Real power of 10 kW with a power factor of 0.8 to the apparent power in volt amps.
S(VA) = 1000 x 10 ÷ 0.8
S(VA) = 12500 Va
Where:
-
- P = Power in kilowatts (KW)
- V = Apparent Power in Volt-amps (VA)
- Cosθ = Power factor in AC circuits
- VL-L = Line to Line Voltage in 3-Phase Circuits
- VL-N = Line to Neutral Voltage in 3-Phase Circuits

Frequently asked questions
The ratio between the VA (i.e. RMS volts time RMS amps) and Watts is called the power factor PF. In other words, volt-amps x power factor = watts. Similarly, KVA*PF = KW, Or kilovolt-amps times power factor equals kilowatts.
In a DC circuit, 1 VA is the equivalent of 1 W. This equivalence means that the power factor of that power supply is 1.
Both kilowatts and volt-amps measure electrical power. Kilowatts are a measure of real power, while volt-amps are a measure of apparent power.
KVA and VA are simply KVA = 1,000VA. The difference between KVA and KW. You need to know the power factor to calculate KW from KVA. Where pf is the power factor.
A volt-ampere (VA) is the voltage times the current feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. Electrical power is measured in watts (W).
