About these units
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.
Exaliter (EL)
An exaliter, equal to 10¹⁸ liters, appears in discussions of planetary-scale volumes, such as estimating water content across extraterrestrial oceans, atmospheric volumes of gas giants, or hydrospheric mass estimates in exoplanet research. Because this unit is so large, it is rarely used in practical Earth-based science except in global summations. However, in cosmology or exoplanet studies, Vast quantities of liquids or gases on super-Earths or ocean worlds may be expressed in EL to maintain manageable numeric magnitudes. The exaliter represents the outer limits of volumetric units still grounded in physical application rather than purely abstract scaling.
