Power result in watts: W

How to Calculate Amps to Watts?

DC = Direct Current
DC (A) to (W) calculation

Formula P(W) = I(A) x V(V)

Power P in watts (W) equals current I in amp (A), multiplied by voltage V in volts.

AC = Alternating Current
AC single phase (A) to (W) calculation

Formula P(W) = PF x I(A) x V(V)

AC three phase (A) to (W) calculation
Line to line voltage

Formula P(W) = 3 x PF x I(A) x VL-L(V)

Line to neutral voltage

Formula P(W) = 3 x PF x I(A) x VL-N(V)
