Amps (A) to kilowatts (kW) calculator.
* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12
The power P in kilowatts (kW) is equal to the current I in amps (A), times the voltage V in volts (V) divided by 1000:
P(kW) = I(A) × V(V) / 1000
The power P in kilowatts (kW) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V) divided by 1000:
P(kW) = PF × I(A) × V(V) / 1000
The power P in kilowatts (kW) is equal to square root of 3 times the power factor PF times the phase current I in amps (A), times the line to line RMS voltage VL-L in volts (V) divided by 1000:
P(kW) = √3 × PF × I(A) × VL-L (V) / 1000
The power P in kilowatts (kW) is equal to 3 times the power factor PF times the phase current I in amps (A), times the line to neutral RMS voltage VL-N in volts (V) divided by 1000:
P(kW) = 3 × PF × I(A) × VL-N (V) / 1000
Do not use typical power factor values for accurate calculations.
