Watt is a unit of power and it measures the amount of energy an item needs to function.

While volts are the derived units for the electric potential difference.

**Formula to convert W to V.**

To convert W to V, we use the following formula.

Amps is short for amperes and is the base unit of electric current.

**Example:**

Calculate the voltage of a light bulb that uses 100 watts and has an amperage of 0.83 amps.

Therefore, the voltage of the bulb is 120 volts.
