This is silly and confusing-yes it all makes sense to an adult brain-you just need to learn the prefixes but teachers didn't understand it or teach it well.
Countries that use the metric system use cm, mm, meter, km, gram, and kg. That's it unless you are dealing with hectares for area. Decimeter, and all the rest are pointless and just add to the chaos.
Learning a different system isn't the thing.... It's grabbing the 'wrong' wrench, crawling under a car, getting somewhat comfortable and finding that you didn't need 9/16", it's 1/2", or is it 12mm, or 11mm, or 13mm or --- how about we all strap 5 or 6 wrenches to our chest?
I don't mind one or the other, fractions don't bother me.... but do we REALLY need to have BOTH anymore?
If the argument is it'll take a decade or two so we shouldn't do it..... 'K... If we had switched 25 or 30 years ago, we'd be a lot closer to needing only one set of wrenches.
I'd still grab the wrong size, but the choices for proper fit would be fewer.
