## How to Convert Volts to Amps

Amperage is a measure of current, which can be found from volts and watts using Ohm’s Law. Ohm’s Law states that current = power ÷ voltage. Power is measured in watts and voltage is measured in volts.

Thus, to find amps substitute the volts and watts in the formula:

amps = watts ÷ volts

**For example**, find the amperage of a 100 watt light bulb at 120 volts.

current = watts ÷ volts

current = 100 ÷ 120

current = .83A

## How to Convert Amps to Volts

Using algebra it is possible to use the Ohm’s Law formula above to solve for volts:

volts = watts ÷ amps

**For example**, find the voltage of a device that uses 120 watts of power with a current of 10 amps.

voltage = watts ÷ amps

voltage = 120 ÷ 10

voltage = 12V
