Ha! I grew up with pennies, shillings, farthings and pounds sterling (pre metrication England). No reason not to go back to traditional measures. I mean who does not know how to work with inches, foot, chains, furlongs, fathoms, leagues and miles? Mind this was 67 years ago, so I am sure I have forgotten a number of them by now from lack of use, but dozens of the books in my library are so priced or reflect such measurements..
Metric will never work in the construction trades.
4 feet wide plywood or drywall is compatible with 16 or 24 inch stud spacing which is determined by the load and the type of wood used. Wire guage is related to the conductor ampacity and the type of insulation used. The insulation is dependent on the environmental conditions (temperature, fire, water, etc). Screw sizes are dependant on alloy strength ( 4-40, 6-32, 8-32, 10-32, 10-20, etc,) Screw and Bolt heads are dependent on the load, and thus fastener size. Changing to metric sizes would double the load in my tool-bag. "Metric" is not easily compatible with a "Huge" installed base. Any benefits would be over shadowed by cost and inconvenience. I about lost my mind remodeling (rebuilding) a 1906 home that had both gas and electric (knob and tube, of course) going to every fixture with no ground. Nothing was "standard". I don't have a clue about metric conduit and pipe sizes and capacity. I have metric in the garage but I don't have to carry those tools around.
What is the supposed advantage to going metric for construction materials? The existing standards are probably arbitrary, but adaption of a new system would lead to conversion errors and component incomptabilities. I don't have enough acetaminophen for that kind of transition.

Canada's pipe and sewer standards are all the same as ours, just labeled in metric in Quebec.
