# Kilowatts to Amps Calculator

Kilowatts (kW) to amps (A) calculator.

## DC kilowatts to amps calculation

The current *I* in amps (A) is equal to 1000 times the power *P* in
kilowatts (kW), divided by the voltage *V* in volts (V):

## AC single phase kilowatts to amps calculation

The phase current *I* in amps (A) is equal to 1000 times the power *P* in
kilowatts (kW), divided by the power factor *PF* times the RMS voltage *V* in volts (V):

## AC three phase kilowatts to amps calculation

#### Calculation with line to line voltage

The phase current *I* in amps (A) is equal to 1000 times the power *P* in
kilowatts (kW), divided by square root of 3 times the power factor *PF* times the line to line RMS voltage *V*_{L-L} in volts (V):

*I*

_{(A)}= 1000 ×

#### Calculation with line to neutral voltage

The phase current *I* in amps (A) is equal to 1000 times the power *P* in
kilowatts (kW), divided by 3 times the power factor *PF* times the line to neutral RMS voltage *V*_{L-N} in volts (V):
