Metric is so easy and logical that I'm sure the USA will some day follow suit. Star Trek is metric too. Just saying...

this is what they told me when I was in grade school, .. in the 1970's!
It's B.S. It's not going to happen. I don't know WHY, , it could, it should, but it won't.
Canada 'supposedly" is all Metric, but they lie! Sure the gas is in liters, the roads kilometers, the food in kilo's BUT, walk into a lumber yard and BAM the metric system disappears! 2"x4" boards 8 feet long, 4 foot by 8 foot sheets of plywood. ( heck even in Europe they sell it in 5' x5' )
Wanna know how thick the sheetrock is? 1/2". 5/8" and 1/4". That's how thick it is. Wanna buy joint compound? It's right over there in the 5 gallon bucket. Sure that has the metric number on it too, but it's STILL 5 Gallons!
And last time I bough them there, the nails were still measure as 16p (16 penny)
