Example of Watts to Amps Calculations

To convert watts (W) to amps (A), you need to know the voltage (V). The formula to convert watts to amps is:

Amps=Watts/Volts

Assuming a common voltage of 120V for these calculations.

Table of Watts to Amps Conversions

Below is a table showing the conversion of various watt values to amps, sorted from smallest to largest, assuming a voltage of 120V.

What Is a Watt?

A watt (W) is a unit of power in the International System of Units (SI). It is defined as one joule per second and is used to quantify the rate of energy transfer. In electrical terms, one watt is the rate at which electrical energy is consumed or generated when one ampere of current flows with a potential difference of one volt.

What Is an Amp?

An ampere (A), often shortened to "amp," is a unit of electric current in the International System of Units (SI). It represents the flow of electric charge across a surface at the rate of one coulomb per second. Amps are used to measure the amount of electric charge passing a point in an electric circuit per unit time.
