We should not just ditch imperial measures, but switch to a hexadecimal number system (with elegant new numerals for 10-15, of course). Not only will arithmetic become much easier, we will also be able to remember 4x4 patterns, and define all 8x8 pixel images with 4 short words!
A system that is based on powers of two allows much more straightforward subdivisions! And if you want to use base 12 for angular values, the conversion is a rather convenient 3/4, not 6/5.
