# Amps to kVA Calculator

Amps (A) to kilovolt-amps (kVA) calculator.

Enter phase number, the current in amps, the voltage in volts and press the Calculate button to get the apparent power in kilovolt-amps:

* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12

## 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)}* *Ã—* 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)} = *âˆš*3
Ã— * I*_{(A)}* *Ã—* 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 Ã— * I*_{(A)}* *Ã—* V*_{L-N(V)}* */ 1000
