About volume conversion
Volume measures how much space a liquid or solid occupies. The metric system centers on the liter and cubic meter, while cooking and fuel use cups, ounces and gallons — and US and UK definitions differ.
US customary volume
US recipes use teaspoons, tablespoons, cups, pints, quarts and gallons. 1 US gallon = 4 quarts = 8 pints = 128 fl oz ≈ 3.785 L.
UK / imperial volume
The UK imperial gallon is larger at 4.5461 L. UK pints (used in pubs) are 568 mL — noticeably bigger than US pints (473 mL). Imperial fl oz is also slightly different from the US.
Cubic units
Cubic inches and cubic feet appear in engine displacement and cargo capacity. 1 ft³ ≈ 28.317 L. Cubic meters are standard in construction and shipping.
