Watts to Volts Calculator

Find the required voltage by entering the power consumption and current draw.

Volts = Watts ÷ (Amps × Power Factor)
1200W ÷ 10A = 120V

How do I convert watts to volts?

To convert watts to volts, you need to know the current in amperes (Amps). The formula is: Volts = Watts ÷ Amps.

What is the formula for AC circuits?

For AC circuits, you must include the power factor (PF). The formula is: Volts = Watts ÷ (Amps × Power Factor).

Why do I need amps to find volts?

Watts measure total power, while volts measure electrical potential. Without knowing how much current (Amps) is flowing, you cannot determine the voltage required to produce that power.
