Yes, it’s from a book called “Uncle John’s Bathroom Reader” and that book was resting on a closed toilet seat in a nation that only kind of uses the metric system in certain situations… however, you’d be surprised how much you can learn after a single visit to any local fast-food joint!
No, I’m not. I live in a commonwealth country that transitioned to metric well before I was born. Recently I’ve had to work with American companies as part of my job.
Don’t get me wrong, the imperial system is horrible, I just wish the metric system had a unit closer in length to feet or inches. Yards would be an annoying unit for human-scale measurements too. Even the name implies it’s usage - it’s for measuring (small) areas of land, which are usually much bigger than humans after all. That’s not a problem in imperial though since no-one would say ‘my pen is 0.1 yards long’, they’d measure in inches instead because it comes out as a nice, human brain-friendly small number like 4 or 6.
