Hopefully not veering too far off topic.
Here in Oz we do get some curious hangovers. For a long time after we went metric milk came in 600ml bottles, and when cartons came in they were also 600ml (which is very close to 570ml - an imperial pint). Now nearly everything has gone to 500ml and 1 litre cartons. Flavoured milk still often comes in 600ml.
Beer however remains just plain silly. Each state has its own regulations and measures. Here in South Oz they doesn’t even make sense. Pubs still sell pints. But they are 425ml, which isn’t even an imperial pint. It is 15 fluid ounces, which is three quarters of an imperial pint. It was a wartime measure to restrict the volume of beer drunk that never went away. All the other states call a 425ml measure a schooner. In SA we call a 570ml measure an imperial pint. People from other states are rather amused at our short measures. Other beer sizes are 285ml (and in SA this is called a schooner) and 200ml (aka a seven = 7 oz, or in SA a butcher). It doesn’t stop here either, but I will.
