About this app
The “Grammage2” app converts the Basis Weight of 8 paper categories to Grammage (GSM) with an absolute minimum of user input. There is no need for the user to know the basic size of a given paper category, let alone entering it. To display conversions from Basis Weight to Grammage values, the “Grammage2” app requires nothing more than entering the Basis Weight of a paper into a Text Field, followed by tapping one of 8 Buttons, each one of which represents a different paper category.
