# Amps (A) to Watts (W) Calculator

This calculator is very useful for converting amps to watts easily and quickly.

How to use this calculator first choose Select current type (DC = Direct Current, AC = Alternating Current Single Phase / Three Phase), then fill the Amps, voltage and other values, then press the Calculate button to get the power value to generate watts.

 Select current type: DC AC - Single phase AC - Three phase Enter current in amps: A Enter voltage in volts: V 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)
