Being able to easily convert between various units makes the metric system the only one worth considering civilized.
Every time I see a wrench labeled with some insane fraction like 18/32 my eye starts twitching. I honestly cannot tell which size is bigger without dividing and converting to decimal.
Human civilization developed all kinds of dumb shit we’ve since discarded. Please let’s discard the idiotic units in my lifetime.
