About these units
Cor (Biblical) (cor)
The cor, also called a homer, is a large ancient Hebrew volume unit often estimated at 220–230 liters. It was used primarily for dry goods like grain but sometimes also referenced for liquids such as oil. Because the cor was large, it played a central role in agricultural recordkeeping, taxation, and royal provisioning. References in the Hebrew Bible describe tribute, temple offerings, and agricultural yields in cors, indicating its prominence in early economic systems. The cor's size reveals the scale of ancient farming operations, where grain harvests needed units big enough to represent substantial quantities.
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.
