When Canada abolished the penny I was advocating for renaming our currency the pound, just so we could divide it up into 20 shillings. Each shilling would of course still be 5¢.
There will be holdouts. In my part of Canada all the rural roads are laid out in a 1 mile x 2 mile grid. Nobody every says a farm is 3.2km away. It's 2 miles. Even changing all the road signs is cheaper than moving roads to make more sense in the metric system.
Otherwise for long-ish distances we're completely metric.
It's weirder when you look at Canada vs USA. Mileage here is usually written L/100km, but back in the day the cars were exactly the same but the mileage in Canada was better because the the US gallon is only ~83% the size of a proper gallon.
My last two offices had showers. No communal room, but the thing I remember most about the last one is the hot water being pumped from the furnaces of hell itself. It took so long go get there, and was so hot once it did I can't think of any other explanation.
