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.
Cubic Foot (ft³)
A cubic foot equals 28.31684659 liters, representing the volume of a cube one foot on each side. It is widely used in construction, real estate, natural gas metering, and HVAC systems. Room ventilation rates, airflow in ducts, and gas consumption often use cubic feet or cubic feet per minute (CFM). Storage capacity for freezers, shipping containers, and building materials also frequently uses this unit. The cubic foot's relationship to the foot makes it practical in industries where imperial length units still dominate.
