There was a beautiful time back when I was young where we tried to change to metric and schools taught us nothing but. Now I’m ~50 years old and don’t even know how many pints are in a gallon. Or feet in a mile. Always forget whether it’s 12 or 16 that’s inches in a foot / ounce to pound. Always have to look that shit up. Because they didn’t teach us that garbage. Ever.
Guess what I NEVER have to look up? The measurements that tell you in their fucking prefixes how many X are in Y. What a concept.
Don’t worry. You likely wouldn’t remember even if you were taught. 5280 feet/mile is just not worth the brain space. Neither is 8 pints/gallon. I don’t think you would convert between the two often enough to make it useful information to just know.
And I do have to look up those prefixes for the less used ones. It’s exa then peta or peta then exa and what’s bigger than them? What’s smaller than nano? I don’t remember because it rarely comes up. But I’m in tech, so it’s starting to more.
Don’t sweat it. It all about using the proper scale of measurement. An astronomer doesn’t care how many miles or kilometers it is to a star. They use light years because the scale is too big for either miles or kilometers.And no one cares how many decimeters there are in a kilometer either.
