And 1m 5dm and 4cm even more so.

You mean like when we write 6'3" for our height instead of 76 inches? Seems to work fine over here. I mean, if you want to write it in the most nonsensical way to make it seem retarded you did fine, but I think 1.54m probably would accomplish everything.

inferior

I never said it was inferior. My entire original point was people acting like one is inferior to the point of not having value is retarded. Which is something almost all Metric users seem to believe, while almost all of us in Imperial land do just fine with using both as per needed when they are most useful.

smallest unit is still so big that we need to start writing it out in fractions

Except this isn't true, we have those units. They just don't see common usage, because Imperial also suffers from the same issue of people sticking with their preferred nomenclature to a point where most people forgot other units. Like the "hand" which is 1/3rd of a foot or the "barleycorn" which is 1/3rd of an inch. Or the "chain" and "furlong" which come between yard and mile. The naming isn't standardized, but all forms of Imperial come from their historical origin instead of having a governing body.

As for why these fell out of usage, I don't know. But we aren't also the ones crowing constantly about our superior and perfect system to anyone else.

Except that one fag up there, but that's why I called him retarded too.
