Cubic feet conversion

Cubic feet

  • There is no commonly agreed symbol for the cubic foot / feet.
  • Various abbreviations are used depending on the context, including (but not limited to) cubic ft, cu ft, cb ft, cbf, ft3, foot3, feet³, ft³.
  • Unit of:

    • Volume (measuring a three-dimensional space)

    Used worldwide:

    • The cubic foot is primarily used to measure volume in the United States, Canada, and the United Kingdom.


    The cubic foot is a unit of volume in the British and US common measurement systems.

    The cubic foot can be taken to describe the volume of a particular material or the capacity of a container to hold such material.


    A cubic measurement is the three-dimensional derivative of a linear measurement, such that a cubic foot is defined as the volume of a cube with sides 1 ft.

    In metric terms, a cubic foot is a cube with sides of 0.3048 meters. One cubic foot is roughly equal to 0.02831685 cubic meters or 28.3169 liters.

    Common values:

    • A conventional shipping container has a volume of 1,360 cubic feet.
    • 19-22 cubic feet is the average size of a refrigerator, enough for a family of four.

    Context of use:

    The standard cubic foot (scf) is used as a measure of an amount of gas under defined conditions (usually at 60 ° F and 1 atm pressure).

    If the cubic foot is applied to a certain fixed material under defined conditions, it ceases to be a unit of volume and becomes a unit of quantity.

    The cubic foot is often used to describe the capacity for the storage of household appliances such as refrigerators, and in the industry for shipping containers.

    Commercial providers of commercial space typically describe the storage units in cubic feet.

    To calculate the volume in cubic feet for a given commodity or space, the length, width, and height must be measured in feet and multiplied.

    For example, a storage unit that is 10 feet long, 6 feet wide, and 8 feet high could be described as having a capacity of 480 cubic feet (10 x 6 x 8 = 480).

    Component units:

    • A cubic foot is the equivalent of 1,728 cubic inches (since a foot is twelve inches, a cubic foot can be thought of as a cube twelve inches on a side, or 12 x 12 x 12 cubes of an inch stacked together).
    • In practice, cubic feet and cubic inches are different units that are not used together.


    • 1 cubic yard = 27 cubic feet
    • A yard is three feet, so you can think of a cubic yard as a cube with sides three feet each or a cube made up of 27 individual cubes with sides one foot.
    • In practice, multiples of cubic feet (as in the oil and gas industry) are described as Mcf (thousand cubic feet), MMcf (million cubic feet), and BcF (billion cubic feet), where Tcf is trillion and Qcf is trillion cubic feet.
