About these units
Acre-Inch (ac*in)
An acre-inch equals 1/12 of an acre-foot, representing the water required to cover one acre to a depth of one inch. Irrigation planners and farmers often use acre-inches to fine-tune watering schedules for crops. Because plants require precise hydration, the acre-inch allows for granular control of irrigation needed for soil management and crop health. Agronomists also use acre-inches to convert rainfall into usable water volume estimates for agricultural regions, linking meteorology with farm management.
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.
