This is not a proper conversion. Cubic centimeters (cc) is a measure of volume. Grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
It depends on the density of the substance in question. In general, 1 cc is equal to 1 ml, so 500 mg would be equivalent to 0.5 cc for water, which has a density of 1 g/ml. If the substance has a different density, the conversion would vary.
1/8 of 4g goes into 500mg
5 1 ml = 1 cc cc is an abbreviation for 'cubic centimeter', which is exactly the same volume defined by one ml (millilitre).
