Just look at fucking feet to miles and try to use your fucking base 12 on that.

You’re comparing the wrong things. You use yards to mile, and you use feet to yards. There are 1760 yards in a mile and there are 1760 feet in one third of a mile. You’re right that they’re not base 12 but the base 16 stuff seems to be used for longer distances while base 12 is used for shorter measurements. Feet are used for measuring room size distances. Yards are used for walking distances. Miles are used for non-walking distances requiring horse (or wheels in the modern day).
