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 the 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 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
