Another small thing I miss is that a liter of water weighs a kg (under reference conditions, I forgot what that was :). Then the specific weight of various materials only has to be known by their "density" (ratio of specific weight compared to water). It makes all sorts of calculations ( and guestimations) easy.
I remember one (and only one) thing from my 7th grade math teacher: "A pint's a pound the world around."
