The only positive thing I see about imperial is that things are easily divisible by 3 and 6, but that’s about it. Then again, if doing the same with metric, you’re usually fine rounding to the nearest millimetre, and if that isn’t accurate enough, it’s probably not supposed to be done by hand anyway.
It’s not nonsense, just old and focused on priorities that don’t matter anymore. A mile was initially a thousand paces. So you send a group of people out, one counts each time their right foot takes a step and after a thousand times they build a mile marker. Bam, roman road system. 1000 strides per mile, 5 feet per stride.
Later the English used the unit as part of their system of measurement, and built the furlong around it, which is the distance a man with an ox team and plow can plow before the ox need to rest. A mile is eight furlong. This got tied into surveying units, since plots of land were broken up into acres, or the amount of land an ox team can plow a day.
When some unit reconciliation needed to be done, they couldn’t change the vitality of oxen, and changing the survey unit would cause tax havock, so they changed the size of a foot.
All the units and their relationships were defined deliberately and intentionally. They just factored in priorities that we don’t care about anymore.
If an alien species has 12 fingers to our 10, would they work in base 12 as normally as we use 10s? Like would their whole system end (or start) with a 0 or equivalent and not end all different?
My maths coherence is too high-school for this thinking, but now its in there.
There’s really nothing special about base 10 numbering, it just feels natural to us. They probably would use base 12 and just have 2 extra symbols for the digits after 9. Example 10 x 10 = 100 in both base 10 and base 12 math. It’s just the translation of that in base 12 to base 10 looks like 12 × 12 = 144 to us.
The Babylonian number system was base 12, that’s why there are 24 hours in a day and 60 minutes in an hour. Afaik they had the normal number of fingers, they were just smarter about making their numbering system divisible.
I’ve banged on about this at length before. I prefer woodworking in inches because I have to divide by 3 and 4 a lot more often than divide by 5. It turns out that the fractional inch system evolved alongside woodworking for a very long time and it solves a lot of the problems woodworkers actually face…as long as you’re not a European scraping in the dirt for something to feel superior about.
It’s funny how the biggest argument for metric is that it’s so accurate but in real life use it degrades to “close enough”. My main problem with metric is that I can’t get my pencil that sharp.
The biggest argument for metric is that it’s consistent. It takes 1 calories to heat 1k of water by 1 degree. State something similar in imperial units.
It’s accurate when you need it to be and gets out of the way when you don’t. And if you do need the accuracy, you have a unit that doesn’t need fractions.

Base 12 is easily divisible by 2, 3, 4, 6 and 12
5,280 ft in a mile is fucking nonsense though

Base 60 can do 2, 3, 4, 5, 6, 10, and 12.
True… Honestly never really thought about it, but I guess it kind of is superior

1 BTU heats 1 pound of water 1 degree Fahrenheit.
How many BTUs are there in a big mac?
No acknowledgement at all that I literally just answered your question?
I see my trap was fallen into.
And isn’t 1kg of water 1L? And 1L is 1000 cubic cm? So a 10x10x10 cube?

Most standard measuring tapes have 1/16th of an inch as the smallest fraction on the tape. 1mm is 1/32nd Which is one is “close enough”? Lol
Edit: 1/32, not 1/64
