> I don't see the point of a duodecimal system of units when a base 10 system is much more elegant. You would never end up with a 1/64th of something in the metric system. Fractions are a hack.

How is base 10 more elegant than base 12?

1/64th might result from a binary, octal or hexadecimal system; duodecimal tens to favour things like 1/3, 1/4, 1/6, 1/9, 1/12 and so on. The elegant thing is that in duodecimal all of those are non-repeating fractions: .4, .3, .2, .14, .01 respectively. Interestingly, in duodecimal 1/5 and 1/10 are non-repeating (this is also true in binary...).

Base 12 is far more elegant than base 10, but the conversions cost make the conversion to French units look cheap--and then we'd need to convert all our units to some sort of French units mark II.

> I guess binary might be an example of that. 2 values is not something that applies to everything, at least not naturally in the way the human mind works, but it is much more efficient for machines to process information, that makes sense.

For day-to-day use, it makes sense to use a system where you can express your age (in years) in one or two digits rather than five to seven. Hence, a hexadecimal system might be preferable as a representation.

Fractions are a hack? 'Cos decimal is so intuitive!

1/3 vs 0.3' ? Much elegance!

1/3+1/3+1/3==1 vs 0.3'+0.3'+0.3'==0.9'==1 or something.
