DC amps to kilowatts calculation

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

AC single phase amps to kilowatts calculation

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

AC three phase amps to kilowatts calculation

Calculation with line to line voltage

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

Calculation with line to neutral voltage

The power P in kilowatts (kW) is equal to 3 times the power factorPF 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
