Amps (A) to volt-amps (VA) calculator and how to calculate. Enter the phase number, the current in amps, and the voltage in volts, and press the Calculate button, to get the apparent power in volt-amps:
Convert amps (A) to volt-amperes (VA) using our user-friendly amps to VA calculator. Simply enter the current in amps, the voltage in volts, and click the button to get the VA conversion.
The apparent power S in volt-amps is equal to the current I in amps, times the voltage V in volts:
S(VA) = I(A) × V(V)
The apparent power S in kilovolt-amps is equal to the square root of 3 current I in amps, times the line-to-line voltage VL-L in volts:
S(VA) = √3 × I(A) × VL-L(V) = 3 × I(A) × VL-N(V)
