Down here, all our food items have the duel measurements on them!For a while. Some gas stations as well as some grocery stores, butchers, etc., resisted and were often fined.
There has been a respite over the last twenty years or so, and we are, measurement wise, bilingual in ways we wish we were in English and French language abilities.
Shops must measure in grams and kilos, but can show prices in both Imperial and metric (must show the metric). Packaging varies, but must have the metric info if nothing else.
In Ontario, we can buy milk in bags (4L total in three bags within a bag- don't ask - the old way was 3 quarts), also in 500mL, 1, 2 and 4 litre jugs/cartons, and of course butter in 454g blocks (i.e. exactly one pound). Everyone knows 250g is just about half a pound, 125g a quarter pound (roughly), etc.
Ask anyone their weight or height and you'll get feet/inches and pounds. Gas is currently 94.3 cents per litre, it's -2 celsius outside, and my house has 2,400 square feet of living space. My yard is 49' x 229', and it's about 6kms from my village to nearby Stratford, Ontario. All road signs (speed, distance) are in klicks/kph.
Wine is mainly 750mL bottles, spirits sometimes in metric sizes, more often than not though they are in odd sizes of mL, as they are in fact the Imperial or American measurements simply converted (i.e. a "forty pounder" - 40 fl oz bottle Imperial is 1.13L, things like rum, vodka and such).
A funny place indeed...
