I've seen several places where this definition is shown, so it must be correct. If you Google for paper weight, there will be at least one site that mentions paper weight in pounds and also in grams / cm-squared, which may make sense to the Europeans reading this but
that would be square-cm.
not to me!
I'm with you!Personally, I have never seen a sensible justification for switching from one arbitrary measurement system (foot, pound, quart) to another arbitrary measurement system (meter, gram, liter).
BTW: one inch now equals 2.54 cm *exactly*, in case you haven't been keeping up! (Used to be approx 2.54 cm.) This is what I mean by arbitrary. Don't like the conversion ratio? Then just change it!
