    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).

    I have also calculated an exact cubic-metre conversion which I've added into the article. So we have the following conversions. 1 international acre foot ≡ 43,560 international cubic feet = 1233.48183754752 m 3 (exactly) = 325,851 + 3 ⁄ 7 US gallons (exactly) ≈ 271,328.072596 imp gal. I have also added a definition for the US survey ...

    This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/cu ft (9.3 kWh/m 3) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline). [22] One GGE of CNG pressurized at 2,400 psi (17 MPa) is 0.77 cubic feet (22 litres; 5.8 US gallons).

  6. Acre-foot - Wikipedia

    en.wikipedia.org/wiki/Acre-foot

    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).

    The imperial gill is further divided into five fluid ounces, whereas the US gill is divided into four fluid ounces, meaning an imperial fluid ounce is ⁠ 1 / 20 ⁠ of an imperial pint, or ⁠ 1 / 160 ⁠ of an imperial gallon, while a US fluid ounce is ⁠ 1 / 16 ⁠ of a US pint, or ⁠ 1 / 128 ⁠ of a US gallon. Thus, the imperial gallon ...

    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]
