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 (Metric) (cup)
A metric cup is defined as 250 mL, differing from both the US cup (236.588 mL) and the UK cup (284 mL). Used extensively in Australia, New Zealand, Canada (informally), and some European cooking contexts, the metric cup provides a clean, simple unit that aligns perfectly with decimal scaling. Its adoption reduces confusion in international recipe exchange and demonstrates the value of standardization for global culinary communication.
