I haven't been there lately but what's the situation in Canada? Beer from Canada can be in bottles that are sometimes 12 floz, but often use the sneaky 1/3 litre, or more likely 330ml! Did you ever see a standard size that went to a larger value on going metric? A fifth is a little more than 750ml. However, it can be remarkable how the old units survive even in countries that use the metric system. I had seen "livre" and "pfund" in Europe, even if they referred to 500g. I know "pfund" is still around but I don't recall "livre" recently.
