Apologies if this is in the wrong stack site, I couldn't think of a more appropriate place for it.
I live in the UK. We're known for having mostly switched to the metric system except for a few specific applications here and there. When it comes to food, the only two food items I can think of that are still measured using the imperial system are milk and beer, both measured in pints.
It seems that the government could have easily mandated both of those industries to start using metric as with every other food manufacturer, so I'm wondering for what reasons this was never done.
