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 (ac*ft)
An acre-foot represents the volume of water needed to cover one acre of land to a depth of one foot—approximately 1,233.48 cubic meters or 325,851 gallons. This unit is foundational in water resource management throughout the western United States, where large-scale irrigation, reservoir planning, and drought analysis depend on acre-foot measurements. For example, major reservoirs like Lake Mead and Lake Powell hold billions of acre-feet. In agriculture, irrigation districts track water rights and allocations using acre-feet, making it a key component of water law. Its scale is ideal for representing the enormous water needs associated with farming, urban expansion, and environmental preservation.
