About these units
Fluid Ounce (US) (fl oz (US))
A US fluid ounce is approximately 29.5735 milliliters. It is not a unit of weight, despite sometimes being confused with the avoirdupois ounce. In beverage serving sizes, cooking, and pharmaceuticals, the fluid ounce provides a flexible unit for small to medium volumes. It serves as the basis for bartending measurements, packaging labels, and nutritional information. Its precise value derives from the US gallon, making the fluid ounce a key link in the US customary volume system.
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.
