Even more bizarre in Australia, which is by now fairly thoroughly metricated, having mostly gone over in 1970.
Height and weight, most people now know metric BUT babies are still routinely referred to in pounds and ounces, and inches - the grandmother effect, I guess, but slowly changing.
Hardware, while always shown in metric, is a mixture. People will want 3.3m of 2x4 timber, or 30m of 1/2" copper pipe.
I reckon it will be another decade or two before all the old guys have been gone long enough.
Beer is no drama - we love our beer down under, and want every ml. But the various measures tend to have names which are neither metric nor imperial, so depending on where you are in the country, you might get a pony, a pot, a middy, or a schooner. Under the influence of British-style pubs you can get a pint, however, though some short-change you with a pissy little US pint.
