I had to look it up. I rather like the water standard at refridgerated temp. This new thing, Planck's Constant, not nearly as exciting.

It is just so sensible using freezing and boiling points of water for your 1-100 degrees reference. Nobody, but moonshiners, is interested in the BP of alcohol that has to be a percentage of a proof gallon because alcohol is so hydroscopic. Without looking it up I couldn't define a proof gallon; I don't even know if it is an American or Imperial gallon.
Actually, when I think about it, that is the sort of traditional system that is always getting amended, by now there is probably an avoirdupois, a troy a continental and an American gallon, and because of a clerical error the Australian one, which has most alcohol.

And three cheers for the Oxford comma.
