Watts to amps calculator

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 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 PF times the current I in amps (A), times the voltage V in volts (V):

P(W) = 3 × PF × I(A) × V(V)
