VA to amps calculator

Volt-amps (VA) to amps (A) calculator and how to calculate.

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

to get the current in amps:

Enter phase #:  
Enter volt-amps: VA
Enter line to line volts: V
   
Result in amps: A

Single phase VA to amps calculation formula

The current I in amps is equal to the apparent power S in volt-amps, divided by the voltage V in volts:

I(A) = S(VA) / V(V)

3 phase kVA to amps calculation formula

The current I in amps is equal to 1000 times the apparent power S in volt-amps, divided by the square root of 3 times the line to line voltage VL-L in volts:

I(A) = S(VA) / (√3 × VL-L(V) ) = S(VA) / (3 × VL-N(V) )
