Frequently asked questions

Multiply current by voltage. 10 amps at 230 volts is 2300 watts for a purely resistive load.

It is the fraction of current that does useful work, from 0 to 1. Resistive loads are 1; motors are often 0.8.

For DC, use a power factor of 1. For AC, include the actual power factor of the load.

Divide watts by voltage and power factor to find the current in amps.

The Amps to Watts Calculator uses the formula: Power = Current × Voltage × Power factor. For example, with current of 10 A, voltage of 230 V and power factor of 1, the power is 2,300.00.

Enter the current. Enter the voltage. Enter the power factor. Read off your power — the calculator updates automatically, with no button to press.
