Amps to Watts Converter (120V/240V)

This converter helps you move between amps, watts, and volts when checking how much load you are putting on a generator circuit.

It’s useful when all you know is breaker amps or device watts and you want to see the equivalent values at 120V or 240V.

Enter any two values and the calculator will estimate the missing third value using P = V × I.
