we are (some reluctantly, but none the less) being drawn into a more metric world.

Milk is still sold by the gallon, but soda is sold my the liter/1.5 liter/ and 2 liter bottle.

knitting needles are no longer willy nilly, US size 6 (formerly about 6.3mm, became 6.25mm, and has now 'shrunk' to 6mm.)

yarn(and fabric is still sold by the yard, not meter, but is labeled in metrics as well as non metrics.

(i've had a "yard stick" that isn't.. (its a meter stick) for years..) and most of my tape measures are dual/marked in inches/cm )

Lots of places, with out an requirements or regulation, billboards announce the temp in F and C... and of course, metrics are taught in schools.. (along with inches/feet/yards)

But its still common (on this board and others like it) to hear of people stating their body weight in 'Stone", or to hear of scores, (of years, of people, of....) and i am pretty sure they still sell eggs by the dozen.. (and lots of other things, invoces still use 'gross' as a common grouping.

and while farmers might sell hectarces of land, they produce (and sell on the commodities market) bushels of grain, and barrels of oil..

Metric are not so universal as we are led to believe. (Speed on hiways is labeled in meter per hour, but places are still miles away!)
