About these units
Gill (US) (gi)
The US gill equals 118.294 mL, representing one-quarter of a US pint. Historically used in measuring alcoholic beverages, the gill once played a significant role in tavern regulations, distilling, and bartending. Its usage declined sharply after Prohibition and continued to fade as ounces and milliliters became preferred for drink recipes and consumer packaging. However, some old cocktail manuals still specify gills, and certain traditional American spirits were originally bottled in gill-based volumes. The gill illustrates the rich historical diversity of volumetric units in American culinary and beverage culture.
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.
