About these units
Fluid Ounce (UK) (fl oz (UK))
A UK fluid ounce equals 28.4130625 mL, slightly larger than the US fluid ounce. It forms part of the imperial system used in cooking, beverage preparation, and older pharmaceutical formulations. Imperial fluid ounces were historically derived from the UK gallon (1/160 of a gallon), distinguishing them from US units derived from a different gallon. Though metric units dominate in the UK today, fluid ounces still appear in bartending, antique recipes, and product packaging that caters to traditional preferences or legacy export markets.
Barrel (US) (bbl (US))
The US barrel is a unit with multiple definitions depending on the industry, though the most common general-purpose US barrel is 31.5 US gallons, used historically for dry goods, ale, and various agricultural products. In practice, the US barrel arose from traditional cask-making, where wooden barrels of different shapes were used for storage and transport. Because their capacity varied widely, different industries standardized the barrel at different volumes. Over time, manufacturers and commercial sectors adopted specific barrel sizes for consistency. Today, the US barrel appears in brewing, winemaking, certain agricultural commodities, and historical documents describing early American commerce. Its varied legacy makes it a fascinating example of an evolving unit shaped by economic necessity and craftsmanship.
