Removed comment about Ems connected to height or width of capital M. This is an incorrect typographic urban legend. An Em may have corresponded to the height of the lead block the letter was located on in letterpress in some faces, but not all.


"Although the names em and en imply a relationship to the width of the capitals 'M' and 'N', in reality they are completely unrelated" (Ambrose 2008) This is restated throughout most typography resources.
