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!

When you multiply, you will often use an intermediate division or multiplication. In a system that is made of multiples of 2, this becomes much easier: in binary, multiplication or division by two are just shifting one digit, and you can easily convert to quaternary, octal, hex.

In a system that uses base 16, you can also mentally arrange the numbers in a 4x4 grid, and use that to not just shift around in one dimension, but in two.
