I've joked that the 16oz US pint was a long-play metric-system scheme to drive adoption of 500ml (~16.9oz) as a measure, a Pavlovian mechanic to trick beer-drinking Americans that the metric system is actually better because it results in more beer. The joke's on them. We're all about 12oz cans! 33cl? pfft...

Germans have it nailed down with the Kölsch Stange, a 200ml glass that so readily disappears that it stays cold and you just get another from the Kranz.

no one drinks it that way, except for those who drive. and believe me, for half a litre in half an hour one yields an acceptable beer temperature
