The US legally switched to metric when England did. It is taught in all schools and used for international trade. But, just like in England there is a mix of imperial and metric units used domestically. If you dont travel internationally, like many Americans, there is little need to use metric. Another generation and there won't be many people left in the US that didn't at least learn metric.

It's not like England in that respect at all. Yes, there is a mix of usage in the UK but it is very limited. People use metric for everything except miles in cars, pints in pubs, and height and weight of people.

From what I have read about metrication, England required all industries to change. The US government doesn't have authority to do that and US industry wasn't going to change all their tooling at great cost if they didn't need to.
