Voltage to Watts Calculator

This calculator helps you understand the relationship between voltage, current, and power. By converting volts and amps to watts, you can determine how much power an electrical device is using. This is a fundamental calculation in electronics.

How to Convert Volts to Watts

The conversion is based on Watt's Law. Simply input the voltage (in Volts) and the current (in Amps) of your circuit, and it will instantly compute the power in Watts.

Power (Watts) = Voltage (Volts) × Current (Amps)
