Enter the current in amps (A), voltage in volts (V), select power factor (PF) from 0 to 1 with a 0.1 step (for AC), then press the Calculate button to get the result in kilowatts (kW).
DC volts to kW calculation
P(kW) = I(A) x V(V) / 1000
The power P in kilowatts (kW) is equal to the current I in amps (A), multiplied by the voltage V in volts (V), divided by 1000.
AC single phase volts to kW calculation
P(kW) = PF × I(A) × V(V) / 1000
The power P in kilowatts (kW) is equal to the power factor PF, multiplied by the phase current I in amps (A), multiplied by the RMS voltage V in volts (V), divided by 1000.
AC three phase volts to kW calculation
P(kW) = √3 × PF × I(A) × VL-L(V) / 1000
The power P in kilowatts (kW) is equal to square root of 3, multiplied by the power factor PF, multiplied by the phase current I in amps (A), multiplied by the line to line RMS voltage VVL-L in volts (V), divided by 1000.
