Amps to Watts Calculator is a free Android app designed by wasim jaffer under the Education & Reference category. This app is a handy tool for anyone working with electrical systems, allowing users to quickly and easily convert between amps and watts.

The app offers a simple and straightforward interface that is easy to navigate. Users can select whether they want to convert amps to watts or watts to amps, and then select the type of electrical system they are working with (DC, AC - Single phase, or AC - Three phase). Once the user enters two matching values, the app calculates the single phase or three phase watts and amps.

It is important to note that the app calculates values based on mathematical formulas and does not guarantee accurate results. As such, it should be used as an estimating tool only. Overall, this app is a useful addition to any electrician's or DIY enthusiast's toolkit.
