...why would you do that? Do you really think measuring cups with scales printed on them are an imperial-exclusive invention?
Yes, I realize that there are metric measuring devices. You are missing the actual point though. Where Imperial units were derived from real-world use instead of mathematical convenience, the ratios are simple and easy to perform.
1 cup flour + 1 egg = noodles. Note that it is 1:1. Convenient and easy to remember. The 'cup' may as well have been derived as 'how much flour I need for one good sized egg'.
1 cup of food = minimum of how much 'food' (gruel) a person should have for each meal, if you don't like that person much. (prison rations, marching armies, soup kitchens, etc.)
2 cups = 1 pint = how much good / heavy beer a person needs to get a satisfied background buzz on. It is more satisfying to simply 'order a pint' than it is to 'order a half liter', even though 500ml > 1 pt.
For anything scientific or needing to be -exactly- communicated, the metric system is king. For simplicity and social measuring - Imperial.
