    Im going to take AP Physics soon, as science is my favorite subject, but math is a bit of a weakness for me and im trying hard to understand and advance, i have a summer packet and after solving the other conversion problems. This has got me stumped i search and i know the answer but the process for getting the answer kind of confusing me basically the question is.

    1g/cm^3 to ___kg/m^3 Im sure this is something i will come on a lot in physics. But my main question is, must i use Dimensonal analysis or do just use the usual metric conversion like normal problems. ( like 1g _ kg)

    Just do the "usual".
    Dimensional analysis isn't required since you're looking at exactly the same "property" in both cases - density.
    In the example given it's easy - the volume has gone up by 1003 so the mass does the same.
    1 million grammes is 1 tonne.
