Canada is supposed to be metric but living next door to the biggest users of the imperial system makes it a little tough to be 100% metric. When we were living in Japan though it was a totally different story. I actually got to use metric all the time…even got to the point where I could estimate length in centimetres and metres. It just so much easier. Imperial seems easier when you are estimating in in feet or inches but as soon as you are estimating in percents of an inch it falls apart…3/8ths or 2/16ths anyone? Seriously…WTH?!?
