As a Canadian who was in her early years at school around the time when SI/metric came in, I have to say that it didn't totally "take" here. I very definitely remember the speed limit signs in my town changing from miles per hour to kilometres per hour, they started out with "km/h" at the bottom so no one would be confused but now just have the number.
Most people my parents' age and older tend to think in Imperial measurements, although many think of temperature in terms of centigrade (which isn't actually metric but works similarly).
Most people my age tend to be a bit "bi" when it comes to units of measure, for example:
-I weigh myself in pounds but my food in grams as per ORChick's example about flour... although I can visualize a pound of butter/hamburger/chicken and think of meat servings based on pounds
-I can translate temperatures fairly well but think in centigrade, my oven shows both temperatures but I have it set to Imperial because that is what most cookbooks use, whereas I have the thermometer in my car set to centigrade
-I personally cook in pinches and scoops and handfuls but if I have to measure I use cups rather than mL (other than weights)
-I measure my height in feet and inches but road distances in kilometres (or hours, which is a typically western Canadian outlook)
-I measure fabric for sewing in metres
-I know there are 12 inches in a foot, 3 feet in a yard, but no idea how many yards in a mile and I always forget how to translate kms to miles and vice versa
-I know there are 8 ounces in a cup, 2 cups in a pint, and 2 pints in a US quart, 4 quarts to a US gallon
-I have no idea how many pounds are in a stone--I think it is a weird number like 14 though, but always have to look it up when my English friends use that term
My teenage kids are a little better with metric, in that they only use metric at school so are better at visualizing their height in metres and their weight in kilos, but they are more familiar with both measurements in Imperial because our bathroom scale is Imperial and they constantly compare their height against their 5'7" tall mother. They cook like I do. And they can't translate between Imperial and metric on any scale whatsoever without a chart or converter, nor do they know how many.
