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). There has been two definitions of the acre-foot (differing by about 0.0006%), using ...
To avoid your rounding errors note that a US gallon is 231 cubic inches and a cubic foot is 12 3 cubic inches so an acre foot is 660 × 66 × 1728 ÷ 231 or 325,851 + 3 ⁄ 7 US gallons exactly. I have also calculated an exact cubic-metre conversion which I've added into the article.
An Olympic-size swimming pool holds over 2 acre-feet of water For larger volumes of liquid, one measure commonly used in the media in many countries is the Olympic-size swimming pool. [47] A 50 m × 25 m (164 ft × 82 ft) Olympic swimming pool, built to the FR3 minimum depth of 2 metres (6.6 ft) would hold 2,500 m 3 (660,000 US gal).
22,956.841139 acre feet 6.228835459×10 9 imperial gallons Alternatively, 35.32 tmcft = 1 cubic kilometer (km 3 ) is the standard unit used by Central Water Commission of Government of India for reporting gross and effective storage capacities of dams in India in National Register of Large Dams (NRLD).
(An acre-foot is about 326,000 gallons — enough water to supply up to three homes for a year). ... state agencies permitted more than 1.2 million acre-feet of groundwater recharge — including ...
A Panamax container ship can consume 63,000 gallons of marine fuel per day at that speed. Fuel use drops sharply as speeds decrease. A container ship can decrease fuel use close to one-third if it ...
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
The state saw 4.1 million acre-feet of managed groundwater recharge in the water year ending in September, and an 8.7 million acre-feet increase in groundwater storage, California’s Department ...
