Amps (A) to kilovolt-amps (kVA)Enter phase number, the current in amps, the voltage in volts and press the *Calculate* button to get the apparent power in kilovolt-amps:

### Single phase amps to kVA calculation formula

The apparent power S in kilovolt-amps is equal to current I in amps, times the voltage V in volts, divided by 1000:

*S*_{(kVA)} = * I*_{(A)}* *×* V*_{(V)}* */ 1000

### 3 phase amps to kVA calculation formula

#### Calculation with line to line voltage

The apparent power S in kilovolt-amps is equal to phase current I
in amps, times the line to line RMS voltage V_{L-L} in volts, divided by 1000:

*S*_{(kVA)} = *√*3
× * I*_{(A)}* *×* V*_{L-L(V)}* */ 1000

#### Calculation with line to neutral voltage

The apparent power S in kilovolt-amps is equal to phase current I
in amps, times the line to neutral RMS voltage V_{L-N} in volts, divided by 1000:

*S*_{(kVA)} = 3 × * I*_{(A)}* *×* V*_{L-N(V)}* */ 1000
