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 ...

A cubic yard (symbol yd 3) [1] is an imperial / U.S. customary (non-SI non-metric) unit of volume used in Canada and the United States. It is defined as the volume of a cube with sides of 1 yard (3 feet, 36 inches, 0.9144 meters) in length.
This translates to a hoppus foot being equal to 1.273 cubic feet (2,200 in 3; 0.0360 m 3). The hoppus board foot, when milled, yields about one board foot. The volume yielded by the quarter-girth formula is 78.54% of cubic measure (i.e. 1 ft 3 = 0.7854 h ft; 1 h ft = 1.273 ft 3). [42]

The cubic foot (symbol ft 3 or cu ft) [1] is an imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom.It is defined as the volume of a cube with sides of one foot (0.3048 m) in length, or exactly 28.316 846 592 L, which is very close to 1 / 35 of a cubic metre).
The cubic inch, cubic foot and cubic yard are commonly used for measuring volume. In addition, there is one group of units for measuring volumes of liquids (based on the wine gallon and subdivisions of the fluid ounce ), and one for measuring volumes of dry material , each with their own names and sub-units.
(Furlongs remained the same, but the rod changed from 15 old feet to 16 1 ⁄ 2 new feet. [10]) In 1324 Edward II systematized units of length by defining the inch as 3 barleycorns, the foot as 12 inches, the yard as 3 feet, the perch as 5 1 ⁄ 2 yards, and the acre as an area 4 by 40 perches. [2]
