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 Amps to VA Calculation:
The apparent power (S) in voltamps is equal to Current (I) in amps, times the voltage (V) in volts:
For example, let’s find the voltamps for a singlephase circuit with 10 amps of current at 220 volts.
S_{(VA)} = I_{(A)} x V_{(V)}
S_{(VA)} = 10 x 220
S_{(VA)} = 2200
Ac Three Phase Amps to VA Calculation :
The apparent power (S) in kilovoltamps is equal to the square root of 3 current (I) in amps, times the linetoline voltage V_{LL} in volts:
For example, let’s find the amps for a 480 volt 3phase electrical circuit with 80 amps of current.
S_{(VA)} = √3 x 10 x 480
S_{(VA)} = 8313
Where:

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

Frequently asked questions
A voltampere (VA) is a measurement of Real power in a direct current (DC) electrical circuit. The VA specification is also used in alternating current (AC) circuits.
Alternating Current) 4000 Volt Amps, is 4000 Watts for a purely resistive load. However, the current flow will be out of phase with respect to the voltage for an inductive (some motors) or capacitive (buried cables) load.
A KVA is simply 1000 voltamps. A volt is an electrical pressure. An amp is an electrical current. A term called apparent power (VA) is equal to the product of the volts and amps.
Watts = Amps x Volts
20 Amps x 120 Volts = 2400 Watts. 10 Amps x 230 Volts = 2300 Watts.
Now 1HP = 1492W=1.492kW=1.492kVA , assuming power Factor=1.
