I'm coming into this conversation late; please forgive me if I'm saying 
something that's irrelevant or obvious to everyone.  (I did check older 
messages, but only a dozen or so.)  Also, I might be being somewhat 
innacurate -- my comment is based on what I remember from learning 
metric in the 1970s.

The link for a meter, or rather a centimeter, is mathematical rather 
than physical: a cubic centimeter is a milliliter.  I don't know how 
this relates to the redefinitions -- do they implicitly redefine a 
liter?  What's the dependency -- is a milliliter based on a centimeter, 
and a gram on a milliliter, or is it reversed, or neither?

Bother.  I was trying to supply an answer, and instead I've asked more 
questions.
