# Kilovolt-amp (kVA)

kVA is kilo-volt-ampere. kVA is a unit of apparent power, which
is electrical power unit.

1 kilo-volt-ampere is equal to 1000 volt-ampere:

1kVA = 1000VA

1 kilo-volt-ampere is equal to 1000 times 1 volt times 1 ampere:

1kVA = 1000⋅1V⋅1A

## kVA to volt-amps calculation

The apparent power S in volt-amps (VA) is equal to 1000 times the apparent power
S in kilovolt-amps (kVA):

*S*_{(VA)} = 1000 × *S*_{(kVA)}

## kVA to kW calculation

The real power P in kilowatts (kW) is equal to the apparent power
S in kilovolt-amps (kVA), times
the power factor PF:

*P*_{(kW)} = * S*_{(kVA)}* *
× *PF*

## kVA to watts calculation

The real power P in watts (W) is equal to 1000 times the apparent power
S in kilovolt-amps (kVA), times
the power factor PF:

*P*_{(W)} = 1000 × *S*_{(kVA)}* *
× *PF*

## kVA to amps calculation

### Single phase kVA to amps calculation formula

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

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

### 3 phase kVA to amps calculation formula

#### Calculation with line to line voltage

The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power
S in kilovolt-amps, divided by
the square root of 3 times the line to line RMS voltage V_{L-L} in volts:

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

#### Calculation with line to neutral voltage

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

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