You can calculate the winding length from the thickness, winding outside diameter, and core outside diameter of polymer film or metal foil, the winding diameter from the thickness, length, and core outside diameter, and the winding weight according to the material from the thickness, length, and width.

(2024/08/6 update: Added metal specific gravity (reference value), API level 14+, compatible with target SDK34)

You can calculate the roll length, roll diameter, and roll weight of polymer films and metal foils.

1. Thickness, winding outer diameter, core outer diameter to winding length
2. Thickness, length, core outer diameter to winding diameter
3. Rolling weight that matches the material based on thickness, length, and width

Regarding the materials used to calculate the roll weight, the specific gravity of plastic films and metals, which are commonly used in the converting industry, are shown as reference values. If you need other materials, please let us know. I will consider adding it.

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

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