UK Miles or Kilometres

Miles. You don't get km until you cross water.

Near me is a road sign.
Width limit 7' , 450m ahead.
Genius

yes, there are a few wackie examples.... luckily a relatively few ...

Petrol by the liter and beer by the pint makes perfect sense.

Its illegal to sell beer in non imperial in pubs, but spirits must be metric

And then there was the greengrocer Nottingham who was arrested for selling bananas by the pound.

No one has been arrested for selling produce in imperial, they have been arrested for using uncertified scales, which can only be certified in metric. It is legal to display prices in both, but the scales must be in metric.

To the OP, unfortunately we still have not completed the conversion to metric, the roads are the biggie remaining.

I recall being told when starting school that there was no point being taught imperial measures because they would be completely obsolete by 1975.

Come across the water from Australia to Canada and buy steaks by the pound or the kilo, gas by the litre (it's a somewhat French-speaking place), mileage measured in kilometres, and beer in pint glasses that look suspicious by any measure. Our dollar is currently worth about nine-tenths of a real US dollar and we cross the border to by cheap gas in a gallon that is not Imperial. We drive on the right, think with our left brains, and vote pretty much straight down the middle. Except when we don't.

Thanks to a change in government when the metric system was being implemented decades ago (a year is still a year, except when it leaps) we got stuck with a mess. Or maybe it's just another aspect of multiculturalism, eh?
