LORE (Story, Background, Character, etc.)
There was a push for base 12 a few years ago that I had read about (for us Humans to adopt). It is interesting to think about how much easier it is to divide into quarters then base 10, but I can just imagine the headache that would follow the switch. A lot of people in the States aren't even willing to embrace the metric system.
I do believe there is a good reason for not switching to the metric system in the States if one takes into consideration the financial headache of switching everything over, ie road signs.
Yeah, it would be a pretty massive endeavor to try and change over.
