The popular use of feet, inches, pounds, and a few of the other old units does persist in parallel to SI. As the joke goes, only in Canada can a river be 200

  Indeed, especially in building materials. Even though common retail softwood lumber wall studs have not been based on a 2" parameter in many decades (they're actually 1.5 by 3.5") and despite the change to the metric system, they are still commonly called two-by-fours, two-by-sixes, etc. Liquid measurements are a very different story. Given the changeover to litres at the gas pump that affected millions of consumers across generations, and given the closeness of 1 litre to 1 Imperial quart, the use of SI with liquids is pretty well complete other than in cooking recipes that usually still use teaspoons and tablespoons instead of millilitres, or grams for solids. As someone who travels in both countries, I don't need to look at a retail grocery item's fine print to tell in which of the 2 countries I'd bought it when a quick look at the labeled mass/weight or volume informs me instantly.
