Amps to VA Calculator

Current (Amps): Voltage (Volts):

 

Single phase amps to VA calculation formula

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

S_(VA) = I_(A) × V_(V)

3 phase amps to VA calculation formula

The apparent power S in kilovolt-amps is equal to square root if 3 current I in amps, times the line to line voltage V_L-L in volts:

S_(VA) = √3 × I_(A) × V_L-L(V)  = 3 × I_(A) × V_L-N(V)
