) Page 57 of the TeXbook says the following:
)     pt  point
)     pc  pica (1 pc = 12 pt)
)     in  inch (1 in = 72.27 pt)
)     bp  big point (72 bp = 1 in)
)     . . .
)     sp  scaled point (65536 sp = 1 pt)

) Don't ask me what (or what use) a scaled point is.

TeX does all its internal calculations in scaled points, giving
more than enough precision for any practical purpose.

Note also that TeX's big point (bp) corresponds exactly to
what many other systems and typesetting languages, including
PostScript, call a point.
