Amps to VA calculator

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

Single phase amps to VA formula

S(VA) = I(A) × V(V)

3 phase amps to VA formula

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

For example, to Single phase amps to VA, when amps = 10 A, line to line volts = 20 V, result in volt-amps = 200 VA

To 3 phase amps to VA, when amps = 10 A, line to line volts = 20 V, result in volt-amps = √3 × I(A) × VL-L(V)  = √3 × 10 × 20 = 346.41016151 VA.
