Note, For higher values like 5×10^{3}, 10×10^{6}, 1.6 x10^{12}, enter the value like this for scientific notation as 5e3, 10e6, 1.6e12, etc.
Conversion Using the Power Formula :
AC Single Phase VA to KW Calculation:
The Real power (P) in kilowatts is equal to the apparent power (S) in voltamps times the power factor (pf), divided by 1,000.
For example, let’s convert 4500 VA with a power factor of 0.9 to kilowatts.
P_{(Kw)} = 4500 x 0.8 ÷ 1000
P_{(Kw)} = 3.6 Kw
Where:

 P = Real Power in Kilowatts (kw)
 V = Voltage in volts
 S = Apparent Power in Voltamps (VA)
 Cosθ = Power factor in AC circuits

Frequently asked questions
A voltampere (VA) is the voltage times the current feeding an electrical load. A kilovoltampere (kVA) is 1000 voltamperes. Electrical power is measured in watts (W)
The voltampere (VA) is the unit of measurement for apparent power (VA) in an electrical circuit. It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes).
A calculate the kVA rating for a singlephase transformer, you'll need to multiply the required input voltage (V) by the required current load in amperes (l) and then divide that number by 1000: V * l / 1000.
A kilowatt is a 2 unit of power representing a rate of 2000 watts of electrical energy.
A calculate voltage from voltamps, simply divide the voltamps by the current.
