    Density data

    Knowing the density of common materials can be useful in a variety of jobs...

    estimating the weight of an object
    finding the volume needed to contain a given weight of a material
    making your own scale weights
    verifying the accuracy of mathematical equations

    For an example of the last one above, see...

    A scale to weigh ungulas

    Code:
    oz/in3 = (2.54 cm/in)^3 * (2.20462E-3 lb/gm) * (16 oz/lb) * gm/cc
    oz/in3 = 0.578035985 * gm/cc
    
    oz/in3 = 0.578036 * gm/cc		1 oz = 28.35 gm
    gm/in3 = 16.38706 * gm/cc
    oz/cc  = 0.035274 * gm/cc		Hg = 13.5462 gm/cc @ 20 degC
    lb/in3 = 0.036127 * gm/cc
    
    Water = 62.428 lb/ft3
