Amps to Volt-amps conversion

Amps (A) to Volt-amps (VA) electric charge conversion calculator and how to convert.

Enter phase number, the current in amps, the voltage in volts, and press the Calculate button to get the apparent power in volt-amps:

A
V
VA

Single Phase amps to VA calculation formula

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)

Three Phase amps to VA calculation formula

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)
