Got to look at the DiaUnitSpinner -- the definition for Points there is
1/72 inch. Here's what /usr/share/units.dat has to say about this:
point 1|72.27 inch # The American point was invented
printerspoint point # by Nelson Hawks in 1879 and
# dominates USA publishing.
# It was standardized by the American
# Typefounders Association at the
# value of 0.013837 inches exactly.
# Knuth uses the approximation given
# here (which is very close). The
# comp.fonts FAQ claims that this
# value is supposed to be 1|12 of a
# pica where 83 picas is equal to 35
# cm. But this value differs from
# the standard.
texscaledpoint 1|65536 point # The TeX typesetting system uses
texsp texscaledpoint # this for all computations.
computerpoint 1|72 inch # The American point was rounded
computerpica 12 computerpoint # to an even 1|72 inch by computer
postscriptpoint computerpoint # people at some point.
pspoint postscriptpoint
So do we go with Knuth, PostScript or ATA? Units are such fun. And I
haven't even brought the six different European points into it:)
