👉 The acre-foot (acf) is a unit of volume used primarily in water resource management, particularly in the context of surface and groundwater. It represents one acre of land multiplied by one foot of water, which equates to 43,560 cubic feet or approximately 12,500 cubic meters. This unit is commonly used to measure large volumes of water, such as those found in rivers, lakes, reservoirs, and aquifers. The acre-foot is particularly useful for quantifying water supply and demand in regions where water resources are limited, helping to manage and allocate water efficiently for various uses like agriculture, municipal supply, and industrial purposes.
