Takes in various information about industrial metal coils and calculates all missing information.

Fields:
* Full diameter
* Inner diameter
* Weight of the entire coil
* Thickness of the sheet
* Height of the coil
* Density of the metal
* Length of the unwrapped sheet
* Total surface area of the sheet

Provide some of these measurements and the app will fill in the blanks! Support for metric and imperial units. Also allows for any density so it can be used for any type of metal, not just aluminum!
