Watts to Amps Calculator
Convert watts to amps or amps to watts using voltage and electrical mode.
EXAMPLE RESULT
Current

DC or single-phase AC only; this does not size wiring or breakers.
How it works
DC current is watts divided by volts. Single-phase AC also divides by power factor, using RMS voltage. Multiply current by the same factors to find watts; use electrical input power rather than mechanical output.
