As the name suggests, an acre-foot is defined as the volume of one acre of surface area to a depth of one foot.. Since an acre is defined as a chain by a furlong (i.e. 66 ft × 660 ft or 20.12 m × 201.17 m), an acre-foot is 43,560 cubic feet (1,233.5 m 3).
It is equal to exactly 43,560 cubic feet, or 325,853.382 U.S. gallons, or 1233.489238 cubic meters". (Unfortunately, it appears that the popular and incorrect calculation of 325,851 or 325,853 gallons per acre foot is being perpetuated throughout the known world! All this because of the lack in ability to do this simple calculation.
It is claimed the process can produce 6,000 U.S. gallons per acre (5,000 imperial gallons per acre; 56,000 liters per hectare) per year compared with 400 US gallons per acre (330 imp gal/acre; 3,700 L/ha) for corn production. [19] In 2015 the project was abandoned. [20]
Corn production in 2009 reached over 13.2 billion bushels, and a per acre yield jumped to over 165 bushels per acre. [33] In the United States, 5.05 billion bushels of corn were used for ethanol production out of 14.99 billion bushels produced in 2020, according to USDA data. [ 34 ]
The size of harvest bins can vary from small trays to half tons bins. In most of Europe, yield is measured in hectoliters per hectare, i.e., by the volume of wine.In most of the New World, yield is measured in tonnes per hectare (or short tons per acre in the USA) – i.e. by mass of grapes produced per unit area.
The census-defined urban area includes L.A., Long Beach and Anaheim, and experiences approximately 490,000 acre-feet of runoff each year, or roughly 437 million gallons per day. Read more: Newsom ...
acre-feet = 4.168 181 825 440 579 584 cubic kilometres: ≈ 916 871 822 916 imperial gallons: ≈ 1 101 117 140 000 US liquid gallons
One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
