    Hi andy

    Yes but beware of the units. They are not in SI.

    Hi andy

    This will help : International System of Units - Wikipedia, the free encyclopedia

    You have to include the unit, which is g/cm^3

    In addition the SI unit of density is kgm^{-3} and 1\, \text{ kg m}^{-3} = 1000 \text { g cm}^{-3}
