the United Kingdom still uses MILES to measure distance, MILES PER HOUR to measure speed, STONES and POUNDS and OUNCES to measure weight, and FLUID OUNCES to measure volume.
OK, I'll bite. Aside from miles to measure distance and speed on the roads, we certainly do not use pounds and ounces in daily life. All meat, food etc is sold in grams. Almost all drinks are sold in litres. Temperature is done in C on the TV and most cookbooks are metric (often with imperial translations).
The only exceptions I can think of are:
1. Beer and milk - we still buy these by the pint (with the metric equiv printed on the label)
2. Roads, as mentioned
3. Human weight is still often done in stones and lbs
Is it perfect? No. However, most people born in the last 30-40 years will have been taught exclusively metric at school. They're comfortable with it.
There is no way that anyone short of a politician would claim that the UK is "Metrified" (or metrificated) and yet they do.
Sorry, I know it's great to paint the US and Liberia as "holdouts". The truth is there are a lot of houldouts that JUST DON'T GET COUNTED.
The UK isn't perfect and we're not all the way there yet, but I don't think people are running around confused. We're getting there (to metric) it just might take a bit longer... The important thing is that we've started!
