Living in Canada, I got used to metric a few decades back (Trudeau the elder) but some people never made the change and probably paid a price in job opportunities
LoL ! I was the other way around.
When I was at primary school the Wilson government committed itself to metrication and we learned everything metric. Then the society was too stubborn and they couldn't get enough shops and companies to stop using pounds, yards and ounces and they rescinded and made it optional. So my generation grew up with a whole load of decimal stuff that was useless in a grocer's shop. We barely knew what an ounce was.
The UK's just getting round to it now.
