Formula & Calculation Steps:
DC: Watts = Amps × Volts
AC Single Phase: Watts = Amps × Volts × PF
AC Three Phase: Watts = √3 × Amps × Volts × PF
AC Single Phase: Watts = Amps × Volts × PF
AC Three Phase: Watts = √3 × Amps × Volts × PF
Converting Amps to Watts
Converting current (Amps) into power (Watts) requires knowing the voltage of the system. This calculator helps determine the wattage rating of your electrical appliances based on their amperage draw.
$$ P_{(W)} = I_{(A)} \times V_{(V)} $$
Power in Watts is equal to current in Amps multiplied by Voltage.
