Pretty much every house in the US is built on imperial. Unless everyone in the country wants to tear down their house and rebuild for solely the purpose of moving to the metric system then there will Imperial stuff tools manufacturing and such pretty much forever. Cars and machinery are Imperial as well but they have much lower lifetimes than houses. I remember reading somewhere that just changing speed limit signs would cost more than 100 Billion to change and that was a modest estimate. I wish I could find where they did the math.
