If we know the amperage (A), we can easily convert watts to volts. For the W to V conversion, we can use the formula for electric power:

If we know the amperage (A), we can easily convert watts to volts. For the W to V conversion, we can use the formula for electric power:

P (W) = I (A) * V (V)

Volt = Watts / Amps

To convert watts to volts, we need to know how many amps does the electrical circuit has.

Example 1: 1 volt is equal to how many watts? If you have a 1 amp circuit, 1 volt is equal to 1 watt. If you have a 100 amp circuit, 1 volt is equal to 100 watts.

Example 2: How many watts in a volt? Amps are the key here as well; in a 1 amp circuit, you have 1 watt per volt. If you have a 10 amp circuit, you will have 10 watts in a volt.

You can freely use this handy watts to volts calculator by inserting W and A. Further on, you’ll find a conversion chart with calculated volts from watts at certain amps:
