The metric system came about around the same time as the U.S. Either way, that intuitive understanding of the imperial system may just come about due to one's growing up with it. I have the same (I assume), innate understanding of the various metric units, given that I was exposed to it all my life. It's easy for me to glance at something and know if it's as big as a centimeter, a couple, perhaps a decimeter or even a meter. The same goes for the volume of something. I think it has more to do with your education, and experience in life, than it's with... the arbitrary way someone came about with those units. Nothing against the imperial system, I understand how difficult it is to leave it now, and no-one could predict if the metric system were to take off at the time. I wish all of us would use only one though.
