As you might know, Canada's official measurement system is metric. I was part of the generation that got caught between learning imperial and metric system when I was a kid and when Canada decided to switch from imperial to metric.
And to this very day, my brain naturally leans on the following measurement preferences:
long distance on road: metric (I have to anyway, it's by law with our road signage in Canada.)
less than 1 metre: I prefer envisioning and estimating in inches.... ie. doing fine artwork,crafts, where I have to cut and measure paper, fabric, etc.
cooking: imperial, but dear god, not ounces, more like cups, tblsp. tsp., etc.
room/home layout: imperial
weight: imperial
This of course drives my dearie nuts, who is more metric dedicated/converted. But then he knows some the alternate engineering measurements from centuries gone by, chains, rods, etc., given his engineering background. I know it's just my lazy brain.
