DC amps to watts:

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:

The power P in watts (W) is equal to the power factor PF times the phase 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:

line to line voltage

The power P in watts (W) 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):

P(W) = √3 × PF × I(A) × VL-L(V)

line to neutral voltage

The power P in watts (W) 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):

P(W) = 3 × PF × I(A) × VL-N(V)
