Not so much a 'weights & measures' issue as a 'scales' one, but I've been looking at Bunnings website and find many exceptions to some of the things you've been saying about goods in Australia. For example, we have here a measuring tape described as "3m/10ft", is dual-scale (Imperial and metric, and has its metric markings in cm, not mm - all of which seem contrary to what you've been saying:There are no non-metric indications on pre-packaged goods sold in Australia -....
Interesting. Most of the Fosters sold in UK appears to be brewed by Heineken in Edinburgh, Scotland.except on some US Imported products where the metric quantities have been included in the US packaging or have been added.
Hardly anyone in Australia drinks Fosters beer. (Made by Carlton, Melbourne)
Not very 'preferred metric', and seemingly somewhat out of line with beer in most parts of the world.Australian beer is (generally) sold in 750 ml bottles or 375 ml Cans - or bottles.
I would think it's a bit of an insult to the intelligence of Australian peoiple to suggest that they would be 'confused' by final digits other than 0 and 5 ! I'm not sure if you're talking only of food and drink etc. bvut, if not, looking again at Bunnings I find things like this...Regulations require that the stated size of all pre-packaged goods be rounded down to the nearest 5 ml (or 5 g) - to avoid "confusing numbers".
Hence "454 g (1 pound) or 568 mL (1 pint) " would not be permitted. ... It would have to be 450 g or 565 ml - unless there was actually more, to make it 455 g or 570 ml.
That clearly is an 'Imperial' 8 feet x 4 feet ( 2,438.4 mm x 1,219.2 mm ) board, which has been marked with metric equivalents, one rounded down to the nearest mm (no nearest 5mm) and the other rounder up to a figure which happens to be the nearer 5mm. That doesn't seem to fit too well with what you've suggested.
I'm surprised they are allowed to call it "a pint"Apart from South Australia, any Hotel Beer Quantity called a "Pint" must be 570 ml (rounded UP)
