For a Chill Dude I do love your fire!
Your thesis is (was before I entered the chat) clear as day. I really don't have much to add here. Unless this might be interesting:
There is a fun thing that arised from moving towards SI units in my country (1920). Some old information was lost from the common citizen. There was a unit Gorčius (around 4 litres). There was another unit Saikas (equals to 6 Gorčius).
The funny part is that we have a saying "Gerk su saiku" which translates "Drink in moderation". Taking it literally, it's slightly funny knowing that the other person just suggested you to drink around 20 litres (usually alcohol is the context).
