And for what it's worth, I've never talked to a person who doesn't agree that the US using metric would be great, the problem is that getting over the inertia of the existing casual measurements is extremely difficult because even when metric is on the label, imperial is the emphasized one (the entire traffic sign infrastructure, the vast majority of cooking implements, decades of cookbooks, most food packaging, medical records systems, drivers licenses, advertising campaigns, the personal fitness ecosystem, entire product names and trademarks). 60 years ago maybe it could be doable, but at this point it's a bit of a lost cause without very much gain.
