About these units
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.
Hundred-Cubic Foot (100 ft³)
This is simply another expression of 100 cubic feet, used in billing systems, engineering calculations, and pipeline monitoring. Where the abbreviation CCF is standard for water utilities, many technical publications explicitly use "100 ft³" to avoid ambiguity. Engineers working on ventilation systems, gas pipelines, or storage capacities may choose this form for clarity in calculations. Its simplicity and direct reference to cubic feet make it a universally understood expression in industries that rely on imperial volume measurement.
