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.
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 agricultural foot was reduced to 10 ⁄ 11 of its former size, causing the rod, pole or perch to become 16 + 1 ⁄ 2 (rather than the older 15) agricultural feet. The furlong and the acre, once it became a measure of the size of a piece of land rather than its value, remained relatively unchanged. In the last thousand years, three principal ...
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.
