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 (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.
