If the United States begins using metric-standard units more for selling foods and the like, then perhaps a half-kilogram (500g) package will be considered to be one new "pound," just as a half-liter (500ml) package will be considered to be one new "pint." That's what happens in Colombia. We ask for a pound of meat, and we actually expect 500 grams. Also we measure fuel in gallons, while the milk is in liters.
