About these units
Cup (Metric) (cup)
A metric cup is defined as 250 mL, differing from both the US cup (236.588 mL) and the UK cup (284 mL). Used extensively in Australia, New Zealand, Canada (informally), and some European cooking contexts, the metric cup provides a clean, simple unit that aligns perfectly with decimal scaling. Its adoption reduces confusion in international recipe exchange and demonstrates the value of standardization for global culinary communication.
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 Today, the US barrel appears in brewing, winemaking, certain agricultural commodities, and historical documents describing early American commerce.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.
