About these units
Gill (US) (gi)
The US gill equals 118.294 mL, representing one-quarter of a US pint. Historically used in measuring alcoholic beverages, the gill once played a significant role in tavern regulations, distilling, and bartending. Its usage declined sharply after Prohibition and continued to fade as ounces and milliliters became preferred for drink recipes and consumer packaging. However, some old cocktail manuals still specify gills, and certain traditional American spirits were originally bottled in gill-based volumes. The gill illustrates the rich historical diversity of volumetric units in American culinary and beverage culture.
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.
