As I understand Canada has gone metric some time ago in its system of weights and measurements. I wonder how the changeover has been carried out as one of Canada's neighbours is not really keen on the metric system at all.
I understand that Quebec has always been metric, obvious reasons really, but how has the rest of Canada coped? Surely, if someone asks you how tall you are you don't say 180 cms or so but feet and inches. Surely, if someone asks how much you weigh, you don't think in kg's, or do you, but in pounds.
What about temperatures? Canada of all countries is a perfect example how the fahrenheit-degree is just rubbish. For the very practical reasons when it is cold it is cleverer to say the temperature is minus something than some 10-15 degrees according to the F-scale.
Construction measurements are still in feet and inches, although distance between cities and speed limits are almost always referred to in metric.
Persons weights I've only ever heard expressed in pounds, but when buying things from the grocery store it's usually expressed in grams or kgs. However, people still refer to some things in pounds like the size of a turkey, the amount of ground beef needed in a recipe, or the weight of a roast. In any case, they're still printed in g/kg on the packaging.
Weather is expressed in C in most places in Canada, but when I lived on the border a lot of people would use F in conversation. Anywhere else I've been in the country, though, people will express temperature in C.
Liquid measurements in cooking are usually expressed in mL or L, but bottles of alcohol are 24oz or 40oz. Wine on the otherhand is expressed as 750mL rather than 28oz. People also use pint for ordering draught at a bar and the menus will typically have oz. as the measurements for their drinks.
Long story short, from what I can tell we tend to use both here depending on the situation.
