In the UK we switched years ago, but many of our rulers and tape measures have both measurements on them. Having been brought up with yards, feet and inches and now happy with metres, centimetres and millimetres, I find myself using whichever seems more convenient. It does get complicated though when I find I have a measurement where the length I've measured in metric and the width in feet and inches.
In Canada you can buy 1/2" plywood as 4' x 8' x 13 mm!!! And since 13 mm is more than 1/2" I guess we should consider it a bargain of more for your money (assuming the price did not go up from when it was sold as 1/2"thickness).
