Template:Molecular formula Hill key/doc
 | This is a documentation subpage for Template:Molecular formula Hill key. It may contain usage information, categories and other content that is not part of the original template page. |
Generates a string version of the molecular formula suitable for sorting in Hill order. Every element that is present is given a fixed-width zero-padded field for the number of atoms present (currently field-width=5, based on largest formula in Category:Set index articles on molecular formulas). It can thus be used as a hidden key in a sortable table (see Help:Sortable tables#Specifying a sort key for a cell).
