Sun may never set on British Empire's pint The Register
In 1970, when I was a teenager in a Midwest town, they taught me the metric system, saying "we'll be switching over from the English system in a few years..."
Enough already. Join the rest of the world. Think with ten fingers, not pecks and quarts.
Start an American revolution. Work and live in the metric system from now on, and let other people figure out what the hell you are talking about. They'll adapt.
This stuff just makes Americans and English look stupid, reactionary, and hostile.
