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.
Kiloliter (kL)
A kiloliter equals 1,000 liters, identical to 1 cubic meter, and is used in water management, municipal planning, agriculture, and commercial storage. Utility companies measure household water usage in kiloliters. Irrigation requirements, swimming pool volumes, and cistern capacities are also commonly expressed in this unit. Its equivalence to the cubic meter gives it flexibility—metric engineers may prefer m³, while public-facing documentation may use kL for clarity.
