Wrong.

> 5280 ft in a mile.

5280 is 12 * 440.

> 16 oz in a pound/pint.

12 troy oz. in a troy pound is also part of the system

> The imperial system is very inconsistent in what can be divided by what.

Inconsistent, yes, "12 only appears in inches in a foot", no.

But what the heck is 440? 440/12 is 36.666666666666667

8292 is 12 * 691 but those numbers are just as meaningless.
