About this app

(Updated 2025/05/20: Added metal specific gravity (reference value), compatible with API level 15+ and target SDK 35)

You can calculate the roll length, roll diameter, and roll weight of polymer film and metal foil.

1. Roll length from thickness, roll outer diameter, and core outer diameter
2. Roll diameter from thickness, length, and core outer diameter
3. Roll weight appropriate for the material from thickness, length, and width

The materials used to calculate the roll weight are the specific gravity of plastic film and metal that are thought to be commonly used in the converting industry, which are displayed as reference values. If you need other materials, please let us know. We will consider adding them.

This is an app I made for work. This is my first time developing an app, not just for Android apps, so there may be bugs, but please let us know if you find any.

The intended users are functional film, vapor deposition, and foil processors who often use polymer film and metal foil.
