Editing Unit cell (section)

== Conventional cell ==
For each particular lattice, a conventional cell has been chosen on a case-by-case basis by crystallographers based on convenience of calculation.<ref>{{cite book | editor-last=Aroyo | editor-first=M.

The number of lattice points, as well as the volume of the conventional cell is an integer multiple (1, 2, 3, or 4) of that of the primitive cell.<ref>{{cite book |last=Ashcroft |first=Neil W. |date=1976 |title=Solid State Physics |url=https://archive.org/details/solidstatephysic00ashc?q=just+fills+all+of+space+without+either+overlapping+itself+or+leaving+voids+is+called+a+primitive+cell |publisher=W.
