US customary versus imperial volume
A US fluid ounce measures volume, not the mass ounce. A US gallon is 3.785411784 liters; an imperial gallon is 4.54609 liters. Recipes and container labels must identify which convention is intended.
A US cup is 1/16 of a US liquid gallon, while a US tablespoon is one-half US fluid ounce. Volume cannot be converted to mass without a material density.
