i do think the idea that the metric system is somehow more rational and sensible than the u.s. customary system is very funny. like, buddy, its only "normal" by consensus; there is nothing normal about basing everything around how far light travels in exactly 1/299792458 seconds, or picking a very undivisible number the basis for your whole way of doing math, or relying on a digital scale to tell you how much sugar to add to your cookies. it is every bit as arbitrary and weird as u.s. customary, you just don't think about it, because it's everywhere.
