What could be akward about imperial units? We measure inches down to the 1/64, 12 inches in a feet, 3 feet in a yard, a lot of yards in a mile. Even more feet in a mile. Then theres also a lot of square feet in an acre, and a certain amount of acres in a square mile. And sometimes someone talks about hectares and I'm not sure if those are metric or imperial.
See, its just that easy.
I honestly google imperial unit definitions regularly when I have to go larger than feet and inches, and I have used the system my whole life. It could be worse though, it could be based on some ligical system of 10's or something.....
