Amps to Watts Converter — Free Online Calculator

Convert amps to watts for DC, single-phase, and three-phase AC circuits. Enter amps, voltage, and power factor.

How to Use This Calculator

Enter the current in amps, voltage, and select your circuit type. For AC circuits, adjust the power factor if needed (0.8 for motors, 1.0 for resistive loads).

The Formula Explained

For DC: Watts = Amps × Volts. For single-phase AC: Watts = Amps × Volts × PF. For three-phase AC: Watts = Amps × Volts × √3 × PF.
