Actually, 1/72 inch (352.8 µm) is what some people call a "PostScript point" or a "DTP point", and AFAIK it wasn't really used (in public) before 1984, when PostScript was first released... The 1959 American(!) definition of a point was 351.36 µm (so slightly smaller than 1/72 inch). TeX uses 1 pt = 1/72.27 inch = 351.5 µm (which is an older, but more "official" definition than the 1959 one). And to make things even more complicated, in Europe the last official definition (in 1975) of a "didot point" was 375.000 µm. ;) -- Jan Claeys -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
