I've never once had to convert miles to feet or vice versa in nearly 40 years (besides a couple test questions in school). It's a total non issue in the whole SI vs US system debate

Ya know what. I like that tomato shit to remember the conversion. I like SI far more than US customary tho

If you want to convert between imperial units, going straight from feet to miles is impractical. You'd be better off knowing the chart of survey units, and they're all small numbers so they're easy to remember.

12 inches in a foot

3 feet in a yard

22 yards in a chain

10 chains in a furlong

8 furlongs in a mile

Of course, i know this because I do 3d art in blender and refuse to set it to metric.

“In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities.” ― Josh Bazell, Wild Thing

the only thing more aggravating than using imperial is having to listen to all the complaining about how metric is better. We get it, bro; it's out of our control at this point

I count a flat 8.
