Other metric measures do have easily understandable correlations (a

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.
