The problem is not "close enough", but that people call one system better than the other one: for no rational reason.
Divide ability for example makes no sense at all. You never have the problem in real live to count 3/16th from a whole unit and it is kind of important that this is a kind of even number. You take a fucking ruler or any other tool to do that: and measure it.
The only "point" those silly people arguing with that is: 1/2, 1/4, 1/8 and 1/16 are kind of easy to do "by hand". And then I backfire to them: and now see, 1/12 is not.
But the imperial morons have stupid ideas why dividing by ... uh, can not even remember the numbers ... 1, 2, 3, 4, 6 ... makes more sense, or is more easy then simply have a decimal system.
In your mind everything is decimal anyway. Or a foot would be 10 inches ... hint, that means 1, 2, 3, 4, 5, 6, 7, 8, 9, XYZ, ZXY, 10. And you need to invent two new signs for XYZ, ZXY.
So, you are doing math in a 10 based number system and have measurements in a 12 based, 16 based, or other based system, but have to use numbers based on 10, to use those other systems ... and you do not see the funny shake heads discrepancy the rest of the world is seeing?
