21 Surprising Things That Have Their Own Units of Measurement
Back in school, you had to learn all kinds of measurements: imperial, metric, kelvin, simon, theodore, etc. Even if you breezed through fifth-grade science, though, you probably can’t estimate today how many millimeters a bookshelf is or the weight of a penny. The chances are pretty good that you can only measure baking ingredients, your penis, and nothing else.
Well, buckle up, because there’s a whole world of measurement out there far beyond what you’ve forgotten. Nevermind imperial and metric — we’re talking completely different systems and sometimes entire metrics invented wholecloth to measure things you had no idea could be measured, let alone by their own unit.
We can speak from experience. Because when user the_real_coinboy66 asked r/AskReddit, “What’s an obscure unit of measurement and how is it used?” the answers blew our minds.
