About these units
Tun (tun)
A tun is a historical large cask unit commonly used in the wine and brewing industries, typically defined as 252 imperial gallons, or roughly 954 liters. It represented one of the largest standardized cask sizes in medieval and early modern Europe. Originally used for transporting wine, ale, and oil, the tun played an important role in commerce and maritime trade. Because taxes and tariffs were often levied per tun, its definition became central to economic regulation. The size also reflected the maximum volume that could be reliably transported in wooden casks without structural failure. Though obsolete today, the tun provides valuable insight into historical logistics, taxation, and the evolution of standardized container sizes in European trade networks.
Cup (US) (cup (US))
A US cup equals 8 fluid ounces, or approximately 236.588 mL. It is indispensable in American cooking, baking, and beverage measurement. Although not an SI unit, the cup remains deeply entrenched in recipes, cookbooks, and kitchen culture. Its intuitive size makes it ideal for measuring flour, sugar, liquids, and many everyday ingredients. American cups differ from metric and UK cups, leading to variation across international recipes, but within the US culinary tradition, the cup is a central volumetric tool.
