Enter the total amps and watts into the calculator. The calculator will display the resulting volts from the sources.

Amp to Volt Formula

The following formula is used to calculate the total number of volts from amps and watts.

V = P / I

  • Where V is volts
  • P is watts
  • and I is amps

Amp to Volt Definition

Converting amps to volts is the process of dividing the total watts by the total amps to yield total volts.

Amp to Volt Example

How to calculate volts?

  1. First, determine the total power of the circuit or system

    Power in electric terms is measured in watts.

  2. Next, determine the current of the system

    This is typically measured in amps.

  3. Calculate the voltage

    Calculate the total number of volts using the watts and amps found in steps 1 and 2.


What is voltage?

Voltage is a measure of electrical force in a system. It can also be conceptualized as an electric potential of a system.

What is current?

Current is the speed, also known as rate, that an electric charge flows through an object. Therefore, the volts can be calculated through the rate and power = potential.
