About these units
Quart (UK) (qt (UK))
A UK quart equals 1/4 of a UK gallon, approximately 1.13652 liters, making it significantly larger than the US quart. Historically used for beer, milk, and household liquids, the UK quart was a staple of British commerce for centuries. In many traditional recipes and food instructions, quarts remain in archival use. The quart illustrates the divergence between US and UK systems following the 18th-century measurement reforms, reflecting how cultural and regulatory environments shape unit evolution.
Fluid Ounce (US) (fl oz (US))
A US fluid ounce is approximately 29.5735 milliliters. It is not a unit of weight, despite sometimes being confused with the avoirdupois ounce. In beverage serving sizes, cooking, and pharmaceuticals, the fluid ounce provides a flexible unit for small to medium volumes. It serves as the basis for bartending measurements, packaging labels, and nutritional information. Its precise value derives from the US gallon, making the fluid ounce a key link in the US customary volume system.
