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 Amps Calculation:
The Current (I) in amps is equal to the apparent power (S) in voltamps, divided by the voltage in volts (v):
For example, let’s find the amps for a singlephase electrical circuit with 2200 voltamps of power at 220 volts.
I_{(A)} = 2200 ÷ 220
I_{(A)} = 10A
Ac Three Phase VA to Amps Calculation :
The current (I) in amps is equal to 1000 times the apparent power (S) in voltamps, divided by the square root of 3 times the linetoline voltage (V) LL in volts:
I_{(A)} = 20500 ÷ √3 x 480
I_{(A)} = 24.65 A
Where:

 I = Current in Amps (A)
 S = Apparent Power in Voltamps (VA)
 V = Voltage in Volts (v)
 V_{LL} = Line to Line Voltage in 3Phase Circuits

Frequently asked questions
Real Power (w) =amps x volts. Thus, a 10 amp socket should theoretically be able to deliver a max of 10 x 220 = 2200 watts.
A voltampere (VA) is the voltage times the current Flow feeding an electrical load. A kilovoltampere (kVA) is 1000 voltamperes. Electrical Real power is measured in watts (W).
apparent power (VA) is a rating definition for DC that is V x I. In an AC circuit if your load is pure resistance the same concept will apply what that means is 1500VA is 1500 Watts.
Apparent power (VA) is the easiest to measure. it is what you get when you measure the RMS volts with 1 meter and the RMS amps with another meter and multiply the 2.
unit of Real Power is a Watt (W). In other terms, we spent one Watt of Power while completing one Joule of Work in one second. 1 Watt = 1 Joule / 1 second.
