We seem to muddle along using a combination of imperial and metric, I don't really notice.
The European Commission announced it was dropping its attempts to bring the UK into line with the rest of the EU over 10 years ago.
Beer and Cider is still sold in pints although spirits are metric, so is milk.
I buy fabric in metres but if altering a garment I think in inches.
Youngsters are taught in metric but still use imperial, hockey pitch is 100 x 60 yards, penalty kick is 12 yards from the goal line, I'm sure if asked the height of someone they'd be more inclined to say 6ft.
Cannabis is typically sold in ounces while cocaine is packaged in grams.
I tend to think of some items by size/look now rather than weight, e.g. a packet of butter, a small, medium or large bottle of milk (no idea how many litres I'm buying), a bag of flour etc.
