We Canadians officially converted to metric in the 70's, however imperial measurements are still in our common usage. There seems to be a difference regionally as well.
In the grocery store, deli meat is sold by gram, meat by kilo, most veg by lbs (so silly!) Liquids are metric, milk, juice etc. Butter is sold in 454gr blocks (1 lb). I find most packaging is imperial sizes converted to metric labels, like the butter.
Temperature as well as distance is metric, but if you ask me I am 5'4"... no idea how many meters! Even on government forms you are given the choice, since most people don't know their weight in kilos.
We generally either mixed up, or bilingual; it depends on how you look at it! We do not however use stones.
