    HxWxD then take that divide by 1728

    12x12x12 = 1728/1728 = 1cf

    Re: Equation?

    All he said was if you are measuring in inches divide by 1728 to get cf.

    Other measurements convert them to inches then you can divide to get 1728.

    Make sure you account for wood thickness, so use internal dimensions.

    Re: Equation?

    I was gonna ask where the 1728 came from, but it seems that 1728 cubic inches is equal to a cubic foot?



    Turn my volume under ten, to keep my speakers from busin'.

    Yes 1728 in^3 = 1 ft^3 because..
    there are 12" in a foot obviously, and so 12" * 12" * 12" = 1' * 1' * 1' = 1'^3
