About these units
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.
Acre-Foot (US Survey) (ac*ft (US))
The US survey acre-foot differs extremely slightly from the international acre-foot due to the slight difference between the survey foot and the international foot. While the distinction is negligible in most contexts, it is important in surveying, legal water rights, and long-term hydrological accounting, especially in regions where large historical datasets were recorded using US survey measures. This variant highlights how even subtle unit differences can have major implications when dealing with huge volumes over long timescales, such as state water budgets and inter-state compacts.
