The first time I ordered 8'x4' plywood sheets since metrication, I asked if they were metric sizes or imperial. They insisted "it's all STRICTLY metric now, you can't get the imperial sizes any more - 2440x1220" (and it's still the same).
It's ALL been strictly metric in Oz for very many years, EXCEPT all the retail hardware stores seem to still sell Asian imperial screws and nuts, while all the wholesale/trade suppliers supply mostly metric.
I see degrees F mentioned twice above. As for "wrong side of the Atlantic", there is no 'wrong' side, but for effect, you could say "Left side of the pond".
