You think that is confusing, go to South Australia, a pint of West End is 15 oz, a pint of Guinness is 20 oz. I drink out of a 40 oz tin (tankard) now and again and that is a Quart Pot.
4 oz and 5 oz are for lawn bowlers to drink quickly before it gets above freezing
7 oz is a glass in some states and an insult in NSW
10 oz is a pot or schooner depending where you are
12 oz is called whatever the pub feels like
15 oz is a pint or schooner depending where you are
20 oz is always a pint except in SA for local beers
22 oz is a Bazza but is not common

No I do not drink Oz beers in Quarts, I have nearly 100 English ales to choose from in bottle.
Is that clear?
