I readily admit naivete, but I think I heard somewhere that in trade
precision has to error to the too much side not �1 only +1.  Certainly the
blanket statement that nothing is packaged to 1 gram precision is doomed to
counter examples.  It all depends on the size of the package.  A stick of
gum is probably to a 1 g precision or tighter, a 5 kg bag of rice, I doubt
it.

BTW when I worked in the pharmaceutical world we had one drug that was so
active the dose was 6 �g.  Formulating tablets to that precision (about �1
�g) was a major challenge.
