A Morgen (Mg) is a historical, but still occasionally used, German unit of area used in agriculture. [1] Officially, it is no longer in use, but rather the hectare. [1] While today it is approximately equivalent to the Prussian morgen, measuring 25 ares or 2,500 square meters, its area once ranged from 1,906 to 11,780 square meters, but usually between ¼ and ½ hectare.

Units for other physical quantities are derived from this set as needed. In English Engineering Units, the pound-mass and the pound-force are distinct base units, and Newton's Second Law of Motion takes the form = where is the acceleration in ft/s 2 and g c = 32.174 lb·ft/(lbf·s 2).

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 ...
As another example, a regulation might limit the concentration of particulate matter to 0.1 grain per standard cubic foot (i.e., scf) of dry exhaust gas corrected to 12 volume percent CO 2. Environmental agencies in the USA often denote a standard cubic foot of dry gas as "dscf" or as "scfd".
It comes from irrigation. If you are going to grow rice in a dry area, you need one acre-foot of water to flood a one acre rice field one foot deep with water.
