I wonder how many people know these numbers. With the level of US education, probably 10%. Not to mention, most quantities will not be exact feet, more like 2’5". Good luck multiplying that, at least 74 cm is easy to type into a calculator.
Anyway, if you ask a European how much a liter of water weighs, 95% will say “a kilo” without much hesitation.
