mc, you didn't need to give them the direct method, you could have created a factory, where you employ them, and you wouldn't lose the monopoly on the product...
You can't post that page and not provide a sauce to go with it.The Japanese Imperialism is starting. Next comes onsen, kotatsu, miso, soy sauce, kewpie mayo, and...
It's actually not that reasonable in this context. Go grab a random object and try dividing into tenths without using any sort of measuring implement, it's almost impossible to do accurately. Now try dividing it into twelfths instead, it is significantly easier, and if you aren't stuck on the the idea of any specific base then you can introduce intermediary units that make conversion possible for people that aren't as educated.This chapter might require a trigger warning for US citizens.
It introduces the outrageously reasonable metric system.
Huh?! How is diving 12 into equal parts easier than 10?! That's ridiculous.It's actually not that reasonable in this context.

Metric works because there were already established measures with which they could scale the units; these people don't have any of that, so they're going to end up having to create an intermediary set of measures anyway. If Ars isn't carefully insistent about the units and providing a proper education, he's going to be the only one using Metric while everyone else is using those intermediary units that are easier for them to work with.

i absolutely love this, isekai metric systemI think this is the first time I've seen an isekai introduce the metric system. Usually it's just baths and rice.
"Half, half, third" makes one twelfth, and the steps can be arranged in whichever order is easiest to measure. The full "Imperial" system (I'll be referencing the US Customary system; different measures, same names, and same conversions except for fluid volume) actually has (or had) units for those steps as well, though some of the names have been lost to time as the units themselves fell out of use; of the ones that remain for length, a "hand" is 4 inches or 1/3 foot, a "short-span" is 6 inches or 1/2 foot, a "span" is 9 inches or 3/4 foot, and a "palm" is 3 inches or 1/4 foot. Going up from the foot there are more similarly spaced units, though beyond the pace, yard and fathom you are mostly left with abandoned Imperial units that got dragged over for surveying and converted to US Customary which left us with some ugly conversions, the "league" even gained a second definition as a length of 3 miles when it was originally a length of 1/2 mile.Huh?! How is diving 12 into equal parts easier than 10?! That's ridiculous.
The only way to achieve easier division is starting with something that is 2 to the power of X, so 2, 4, 8, 16, 32, 64 etc. Literally any other number is going to hit a brick wall of an odd number if divided into two (which is the easiest way to divide into equal parts).
That being said, dividing reasonably large numbers is pretty easy no matter what base you use. You just need to fill the length with some very small objects that have the same dimensions, count them once they fill the whole length, and divide by ten. If you use small enough 'pixel', this will offer you more than sufficient accuracy for literally anything that people in a medieval-like society would need it for.
While this can work for millimeters as well, the technology to make and use small enough grains that are identical simply wouldn't exist in such a society, so centimeters is the largers dimension that could be feasibly divided (so millimeter would be the smallest dimension they could achieve with acceptable accuracy).
As for the comparison of bases between 10 and 12, 10 is vastly easier to use in math of any sort as any division or multiplication by 10 is just moving between the digits left and right, adding or removing 0's or moving whatever interpunction you use to divide the whole number with fractions in your country.
No, they're the right boxes. The image is just confusing. Looking at the image, they indicate and label the large group with what they're taking from it, then indicate and label the actual unit. The labelling of "one tenth" and "one meter" is consistent with the way they also labelled "one hundredth" and "one centimeter"
