DC amps to watts calculation

The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V):

P_(W) = I_(A) × V_(V)

AC single phase amps to watts calculation

The power P in watts (W) is equal to the power factor PF times the current I in amps (A), times the RMS voltage V in volts (V):

P_(W) = PF × I_(A) × V_(V)

AC three phase amps to watts calculation

The power P in watts (W) is equal to square root of 3 times the power factor FP times the current I in amps (A), times the line to line RMS voltage V_L-L in volts (V):

P_(W) = √3 × PF × I_(A) × V_L-L(V)
