AC single phase watts to amps calculation. You can calculate watts from amps and volts. You can’t convert amps to watts since watts and amps units do not measure the same quantity.

Watts is also known as volt-amps and is typically used in conjunction with AC power.

Enter under volts; Enter under watts; Click calculate; You get 1. Calculate watts, volts, amps ohms, fill in any fields and the rest will be converted. You will need to know the amps and the volts in the power source. To determine the wattage, use a simple multiplication . Input any two values of Voltage (V), Amperage (A), Wattage (W), or Ohms (Ω) to find the other two missing values. Calculate voltage, current, resistance, and power.

Read our convenient amps, volts and watts conversion guide with a handy calculator to convert between units without using a formula. They are Power (P) or (W), measured in Watts, Voltage (V) or (E), measured in Volts, Current or Amperage (I), measured in Amps (Amperes), and Resistance (R) .
