No need for scare quotes, US customary units are a thing. A US customary cup is, at least, quite standard at 8 fluid ounces. This is more standardized than the unit of measure used in British recipes and whatnot. The issues surrounding volumetric measurements for dry goods is an entirely separate matter. 240 mL of apricots is just as useless as 1 cup of apricots.
