As an American, I understand that metric is better for a lot of things. It also would cost a metric fuck ton (ha!) of money to switch over, and it just really isn’t a priority when things work just fine for us here. It’s not like we are constantly running into problems that would be easier to solve by using metric, and the people in the few professions that do run into those problems frequently just use metric.
The original idea behind imperial units is actually quite nice. They used 12 inches in a foot because you could divide it in so many ways without using decimals. You can take 1/2 of it, 1/3, 1/4, and 1/6 without ever needing decimals. It’s great for mental math with small numbers. That obviously is no longer the most important thing anymore, as we all have calculators with us at all times, and we deal with much bigger numbers on average than they used 200 years ago.
We all still use 360° in a circle for this exact reason. It can be divided up in 22 different ways (excluding 1 and 360 as factors).
