Kilowatts (kW) to amps (A) calculator.
* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12
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):
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):
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 VL-L in volts (V):
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 VL-N in volts (V):
Do not use typical power factor values for accurate calculations.
