Enter the total current in amps and the total voltage in volts into the calculator. The calculator will convert the amps to watts.

Amps to Watts Formula

The following equation can be used to convert the total number of amps into the total number of watts. In other words the total current to total power.

 P = I * V
  • Where P is power in watts
  • I is the current in amps
  • V is the voltage in volts

To calculate watts from amps, multiply the amps by the voltage.

Amps to Watts Definition

Converting amps to watts involves multiplying the total current in amps by the total voltage to yield the total watts.

Amps to Watts Example

How to calculate watts from amps

  1. First, determine the total current

    Measure or calculate the total current of the circuit in amps.

  2. Next, determine the total voltage

    Using a voltmeter or equation, calculate the total volts of the circuit.

  3. Finally, calculate the power

    Calculate the power, also known as the total number of watts.


What are watts?

Watts are a measure used in physics to represent total electric power. This value is derived from the current and electric potential of the system.
