Twelve and Sixty are each divisible by one more integer respectively than their ten and one hundred counterparts.
However, the last bit -- 12 and 60 are much more convenient units to divide by -- is fecking rubbish.
I don't think there will be metric time any time this millenium because of the hassle of conversion. Everyone uses the 24 hour day, 60 minutes per hour concept now, to change it would be expensive and pointless.
