“A pint’s a pound, the world around.” Except...what’s a pint? And, for that matter, what’s a pound?
Here in America, we take for granted our feet, our inches, our Fahrenheit temperatures...we even watch our pounds.
But, leave this country, and it’s pretty clear we’re on an island - an island the rest of the world would measure in meters...an “international standard” that we’re still resistant to.
