You do realize that the most common weights and measures in the world is metric?
Only in uncivilized and barbaric parts of the word where they don't understand that the word
football refers to American Football (NFL - National Football League), and that that hideously boring sport the barbarians play with their feet is properly called
soccer.
The problem with the metric system is it's wrong.
Millipedes don't have 1000 legs.
Centipedes don''t have 100 legs.
And water doesn't boil at 100 degrees (it boils at 212 at sea level). !00 degrees is just luke warm, and leads to DMS and infections
That's why good beer is only made in America.
It's also less acuurate -
You ask your local drug dealer:
" I want an ounce of Mexican red"
vs.
" I want 28.3495 grams of Mexican red". Now he's got to whip out his jewelrs scale and in the time it takes to try to accurately weigh you both get collared.
