It's actually even worse, especially if you take European conventions
into account.

"Conventional" Amrican		72.27 ppi
PostScript and some others	72 ppi
Didot point			67.54 ppi

And then there's the pica (12pt), which is therefore sometimes 1/6th of an
inch, and sometimes 1/6.022th of an inch, the cicero, which is 12 didot
points, ...

For example, I usually use TeX to format things, and so when I ask for
a 10pt font in TeX, it turns into a 9.96264 point font in PostScript.
There is very little visible difference, but my documents take a while to
start up, since there usually aren't any 9.96264 point fonts in
the font cache :-).
