The units in question are pt = 100:7227 in (point) in = 254:100 cm (inch) pc = 12pt (pica) cm mm bp = 1:72 in (big point, same as PostScript's idea of point) dd = 1238:1157pt (Didot point) cc = 12dd (cicero) sp = 1:65536 pt (scaled TeX point, smallest representable dimension in TeX) TeX also has dimensions ex and em, but those depend on the current font size. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
