Metric is interesting in that it was built upon scientific relationships but those relationships are meaningless for 99% of people and are, in and of themselves, arbitrary. If we ever came across aliens their measurements would be completely different because metric is ultimately based off of the circumference of the Earth (that's the basis of the meter).

Of course those snobs have tried to "standardize" it in idiotic ways, like defining the meter as "one three hundred millionth something of the time it takes light to travel one second" but that's retarded. They had to do it because the meter has always been a fucked-up measurement.

It's a big fat "who cares".
