It makes me laugh too. In Junior school about 100 years ago they taught us imperial and metric, then said we would be completely metric 'very soon!' 😂

When I sell fabric in our shop, we have to sell metric quantities by law and also all our systems are metric based. However, we will talk to some of our older customers in imperial equivalents, so they feel more comfortable.

Just a random thought - No matter what part of the world, and no matter how many wheels the vehicle has, what system is used to measure the diameter of those wheels? Dry roads to everybody. Michael.
K2-K6:
You're right, forgot about those.
They are inches diameter, aspect ratio expressed as percentage of width, which is mostly in millimetres now! Not confusing at all :)
We drive around in miles still, but buy fuel in litres.
Aren't mainline railways all the same, apart from those cunning Spanish chaps?
And off down the pub for a pint of oldsquirrelbollocks, or is that now officially, I'll have a 568.261ml of old peculiar rats nadgers please barkeep.

We can never go completely metric - there are just too many products/protocols out there that are Imperial only.
All pedal cycles use 9/16" BSC (cycle thread or CEI) on the cranks and pedals, and it can never change, otherwise old pedals won't fit new bikes.
All taps use 1/2" or 3/4" BSP (pipe thread) - even in Europe.
A lot of pipes in the UK are 38 mm (a nominal value for 1½").
All socket drives are 1/4", 3/8", 1/2", 3/4" or 1".
Tyres are always in inches for the diameter - I was talking to a tyre fitter who claimed he didn't know Imperial until I pointed tyre diameters ;).
All aircraft fly in feet (Flight Level 350 = 35,000').
Minimum tyre tread depth is 1.6 mm, but that's just 1/16" translated to metric.
All fence panels are 6' wide.
Standard house doors are 2'6" wide, but I did see a DIY store selling 762 mm doors :).
Printer quality is measured in DPI (dots per inch).
There are probably dozens more examples, but I've probably bored you enough already.
