ac·ft/d
acre-foot per day
Volumetric flow rateexact by definition
The acre-foot per day is exactly 1233.48183754752/86400 cubic metres per second, about 14.28 L/s. It is the delivery unit of irrigation districts and water rights administration in the western United States, where storage is in acre-feet and the release rate follows naturally.
Watch out: One cubic foot per second flowing for a day is 1.9835 acre-feet, so the two units of western water are almost but not quite in a ratio of two. Ditch riders use the approximation and accountants do not.
