oz to Cups Converter
oz to Cups. Example: Value in US fl oz: 2.5 gives 0.3125 US cup. Uses US customary liquid volume, with US gallon=3785.411784 mL, cup=1/16 gallon, tablespoon=1/256 gallon, teaspoon=1/768 gallon, fluid ounce=1/128 gallon. US legal nutrition cups, metric cups, Australian tablespoons and Imperial measures differ. Ounces here are fluid volume, not mass; density is not inferred.
