Interesting fact of the day, about 78% of the worlds GDP is produced in countries using the metric system. 22% of the worlds GDP is produced by the imperial system (the system the USA and UK and a few other countries use).

@freemo The UK is predominately metric now. Imperial is used for road signs & by the older community but for little else.

@Perrywong That has not at all been my experience when traveling to or interacting with people fromt he UK.. Just yesterday my friend from the UK (about 25) told me her weight and it was in stones.

@freemo Yes, I still measure my weight in stones & we still measure milk in pints, although the bottles display the volume in litres, 2.272 litres for a four pinter, if memory serves. We also still serve beers in pubs as pints but spirits & wine, in those same pubs, are in millilitres. Almost everything else i can think of is in metric but, again, there is a legacy from measuring in imperial. For instance, sausages are bought in packs of 454g which is basically a pound of sausages.
