In the UK we switched from imperial to decimal measurements decades ago. That’s the official line. What actually happened is that we found it hard to switch and even the latest generation are confused.
Stand on the scales and you can report your weight in pounds and stone or kilos. Measure your new carpet in meters or feet and inches. Don’t get me started on how we measure a field.
If visiting the UK and you have a question about measurements, prepare to have a converter at hand.
