Amps to Watts Calculator
Convert amps to watts for DC, single-phase AC and three-phase AC circuits, with power factor.
Enter your values and press Calculate.
How to use the Amps to Watts calculator
Find out how much power a circuit or device can deliver from its current rating.
Formula
DC: P = I × V. Single-phase AC: P = I × V × PF. Three-phase AC: P = √3 × I × V × PF.
