Enter the current in amps (A), voltage in volts (V), then press the Calculate button to get the result in kilovolt-amps (kVA).
Single phase Amps to kVA calculation
kVA:
S(kVA) = I(A) × V(V) / 1000
The apparent power S in kilovolt-amps (kVA) is equal to the phase current I in amps (A), multiplied by the RMS voltage V in volts (V), divided by 1000.
3 phase Amps to kVA calculation
Line to line voltage
kVA:
S(kVA) = √3 × I(A) × VL-L(V) / 1000
The apparent power S in kilovolt-amps (kVA) is equal to square root of 3, multiplied by the phase current I in amps (A), multiplied by the line to line RMS voltage VL-L in volts (V), divided by 1000.
Line to neutral voltage
kVA:
S(kVA) = 3 × I(A) × VL-N(V) / 1000
The apparent power S in kilovolt-amps (kVA) is equal to 3, multiplied by the phase current I in amps (A), multiplied by the line to neutral RMS voltage VL-N in volts (V), divided by 1000.
