it's like your measurement systems.... way too complicated...
fractions of an inch sucks...
adding inches to the foot sucks...
then there is the yard, wich i have no clue where it comes from (other than football

)
the mile is also odd, and always on our speedmeters, wich is annoying...
and there is the quantities...
the ounce, wich is for shooters...
with a pint, other than the british beer size, i don't know any practical use...
then the gallon, wich is way too confusing with all the types of gallons...
there is also your temperature system, but that's more a matter of opinions and "precision"(wich is not that really important if you put a decimal in the celcius measurement)
most of the world has converted to the metric sstem... it's so much more simple to add and substract by 10 instead of having some different weird way of deciding that...
OMG.. i just went over to wikipedia... it's so much worse than i thought... there is all those units that i never heard of before... like a "thou" or a "furlong" and a "league"....
so it takes 1000 thou to make an inch
12 inches to make a foot
3 foots to make a yard
220 yards to make a furlong (who the fuck decided it took 220 yards for another unit.. it's dumb)
8 furlongs to make a mile
3 miles to make a league
that is completely fucked up and overly confusing... so... how many thou is there in a furlong? you have 30 seconds to answer without any help... like hell you could answer!
