About these units
Tablespoon (US) (tbsp)
The US tablespoon is defined as 14.7868 mL, though commonly rounded to 15 mL in nutritional labeling and informal cooking contexts. In American cooking, the tablespoon is indispensable for measuring oils, spices, and small liquid quantities. It is also widely used in medicine for dosing liquid medications at home, though modern practice increasingly recommends milliliters for clarity. Its relationship—3 teaspoons = 1 tablespoon and 16 tablespoons = 1 cup—allows American cooks to scale recipes easily, making it a cornerstone unit of the US culinary measurement 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.
