Virtually all products in America have volumes and weights listed in metric, alongside the customary units. Even those packaged specifically for America. Many beverages specifically are packaged in whole number liters, with oddball fluid ounces listed next to that. e.g. a 1 liter / 33.8 floz bottle of coke. Where customary units seem strongest is in civil/mechanical engineering and adjacent trades, road signs (all in miles), and weather reports in Fahrenheit.
