Queen Anne Wine Gallon (1707)
Modern equivalent
3.785 litres
A 1707 statutory standard established to resolve maritime customs disputes, which later crossed the Atlantic to become the standard US Fluid Gallon.
Enacted under Queen Anne to bring legal clarity to international commerce and tax collection, this historic 231 cubic-inch measure provided a definitive volumetric standard for high-value imported beverages. Its precise geometric definition ensured consistency across customs ports before later adoption as the foundation of United States liquid measure.
