# Amps to kVA Calculator

 Select phase #: Single phase Three phase Enter amps: A Enter volts: V Result in kilovolt-amps: kVA

Amps are a measure of electrical current in an electrical circuit. kVA, or kilovolt-amps, are a measure of apparent power in a circuit, and 1 kVA is equal to 1,000 volt-amperes.

Because amps and kVA are different things in an electrical circuit, the voltage is also needed for the conversion. By also using the voltage, it’s possible to convert amps to kVA using the electrical power formula.

## 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 VL-L in volts, divided by 1000:

S(kVA) = 3 × I(A) × VL-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 VL-N in volts, divided by 1000:

S(kVA) = 3 × I(A) × VL-N(V) / 1000
