Don't you guys switch on us now - I'm just re-learning the "standard"!
We used metric back in Canada. Technically. To the younger generation, I guess the transition is done, but for people in their 30s and 40s, not so much...
Even in Canada, I'm 6'3" , 200 lbs. For most of my life, Montreal was 400 miles from where I lived. If you travelled, you'd figure out the "miles per gallon". There was a quarter of milk in the fridge. And so on...
For the longest time, the only place where we actually used the metric system was in school. But eventually, some things did come into effect - the ones people had no option but to learn. When they sell gas by the liter and speed limits are in km, you do make the transition.
But most people still calculate their height and weight in feet, inches and lbs.
