You make my point for me! The answer is, "Who cares?" The average person in
daily life has NO need to know the number of ounces in a ton. It's as
meaningless as the diameter of the solar system in Angstroms.

Originally, yes, but my point is that that's as arbitrary a measurement as
the length of the king's foot. The circumference of the Earth is NOT 40kkm
anywhere -- it's just a made-up number.

Cool! That I didn't know!

Pish. If I take my 17/32" wrench and write a "16" on it, it's just as easy
to find in the drawer. The actual size of the tool is irrelevant. Look at
letter drills (Size A?) for an example.

People try to sell the metric system saying it makes life easier. But most
people who found a pint just right at the pub find a liter too much and 500
ml too little.
