Slightly off topic, but this reminds me of why sheet goods like plywood and drywall are 4 ft wide. 4ft = 48" which is evenly divisible by 2, 3, 4, 6, 8, 12, 16

4ft = 48" which is evenly divisible by 2, 3, 4, 6, 8, 12, 16, and 24. This makes math easy and significantly minimizes cutting and waste.
- lmpdev 3y agoI notice target voltages that engineers often pick similarly highly composite integers 3, 9, 12, 24, 48, 56, 72, 96, 480, 600 etc There are many other factors which result in these as well though

- eternityforest 3y agoI did some research on this for my CSS framework, I didn't want to have a max-h-1rem type value for every single number, just a small subset that is easy to remember. 5-smooth numbers and practical numbers overlap with the highly composite, but include more of the common "Numbers you see everywhere that people seem to like".

- Fire-Dragon-DoL 3y agoIn Europe we are obsessed with anything divisible by 5, so if you made something 48cm long, it would be annoying
- BrandoElFollito 3y agoWe are obsessed with anything divisible by 10, which is our counting base. So a decimal system is most logical. It is highly unfortunate, though, that we used the number of our fingers for that base. Have we gone for the phalanges (sans content then with a thumb) we would end up with 12, divisible by 2, 3, 4, 6. Since we would just use one hand for counting, we would easily end up with 12x12=144 without any effort.
