It’s a discussion I have with a friend sometime… in actuality in the metric system scale of 10 works fine. 12 scale is only necessary for imperial measurements because there’s nothing smaller than an inch, having 3.2 inches literally cannot be represented on a ruler. So you start working with like half inches, quarter inches, even 1/8th of an inch which sounds like a headache. Note that inches are on a scale of 12 but not base 12.

Since in metric you can “create” units as needed (they already exist we just don’t use them most of the time), you can quickly and safely measure 3.2cm. You can also still do division, it just won’t need to be represented by fractions. If you have a 10cm long board and want to cut it in four, each cut will be 2.5cm long, not a quarter of a unit long.

With that level of detail you can get to very minute decimals like 4.52cm, although for most daily uses you don’t need to count anything smaller than mm. The amount of times I’ve had to use um (micrometers) in my life was… 2?

So with this for example

Skilled Tradesmen will use imperial/base 12 systems for manual work. i.e. Construction, carpentry, etc. as the ability to use thirds and quarters of a unit without relying on fractions

With simple divisions and multiplications I have the ability to achieve any measure I need. I assure you our tradesmen are not any slower or worse than those in the US haha

It also allows a pretty cool conversion since by standard 1l of water weighs 1kg.

Base ten is trash and a glorious socialist utopia wouldn’t use ivory tower measurements that aren’t actually useful for performing labor

I figure you’re probably joking but I don’t think any lab worker does their measurements in fluid ounces and cups 😬
