Based on practical experience (moving to another country several times
over the years), the disruption in day to day life is minimal. Pretty
soon, you ask for a half or third kilo of cheese instead of a pound.
You know that 10 degrees is cool, chilly in the shade, 20 degrees is
nice, 30 degrees is pleasantly warm, and 40 is hot. -20 is where spit
A yard and a meter are about the same, so if you're buying fabric or
rope or wire that works out pretty well.
A square meter is about 10 square feet, so if you're looking at
apartments, 40 sq m is smallish, 200 is palatial.
People by gasoline by money amounts (or "fill it up"). Back when gas
started to go over $1/gallon, some stations changed their pump to read
in liters, and it was only moderately inconvenient, and after a while
you get used to it.
I think if we did the "massive cutover" there would be whining and
complaining for about a month or two.
In a year, all the recipes would be printed in metric, except for books
specializing in archaic styles.. but those exist today.. my wife has
screwed up more than once using a recipe originating from her (English)
mother or grandmother.
If you buy a graduated measuring cup today it likely has both metric and
US Customary units on it. Yes, you need to know that a teaspoon is 5ml
and tablespoon is 15ml, but that's not exactly an ordeal.
The tricky thing is manufacturing and customary sizes. That 1/4-20 bolt
has a long and enduring history and we'll be making them for decades to
come. But over 10-20 years, instead of bolt bins at the local hardware
store having mostly customary units with a smaller section for metric,
we'll have more metric, with a smaller section for customary.
Most folks have both sets of wrenches and hex keys, etc. (or, they just
use the adjustable wrench or those ChannelLok serrated pliers, so they
can rip the corners off any nut, metric or US)
