Voltage to Watts Conversion | Amp Voltage Watt Calculator

The Voltage to Watts Conversion Tool allows users to convert volts, watts, and amps using an online calculator. Watts are also known as volt-amps and are a unit of electrical measurement typically used in AC power circuits. This converter works by filling in any of two of the three fields to calculate the value of the third field.

Here is an example of how this conversion tool is used. A security system installer may need to calculate the distance cable that a power cable can be run to a CCTV camera or HD security camera and they first need to calculate how many amps a 24V AC power supply outputs. Typically, 24V AC power supplies have VA (voltage amps) ratings and not amps. For example a 24VAC50 power supply is 24 volt, 50 voltage amps.
