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!
I mean yeah, Metric scales.
Everything can be scaled. 1 can be two halves & 3 can be 12 .025’s. or we can all just agree that everything is based on various systems of measurement invented by humans who can hardly agree on their own origins and the purpose of their existence, or even the right to exist.
