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!
Hey it’s me some French guy on the internet. I think the main argument for the metric system is how they all connect together in a simple way. 1km is 1000m, one cube meter of water is 1000L, etc. We don’t really care what the base unit is.
