Not sure what a cubic gram is.
Grams per litre is simple a measure of density. Whatever cubic grams is, it is not a measure of density and so these two measure different things. Therefore, according to the rules of elementary dimensional analysis, conversion from one to the other is not valid.

Gases normally have a density of a few grams per liter (i.e., per cubic decimeter), at most. Air, for example, has a density of about 1.2 grams per liter, at standard temperature and pressure. The standard SI unit for density would be kilogram per cubic meter (which actually happens to be equivalent to grams per liter!), but many people are still accustomed to specify the density per liter, not per cubic meter.
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
There are 1,000 milligrams per gram. 0.2 grams*(1000 milligrams/gram) = 200 milligrams
The numbers are equivalent. For example, 5 grams per 100 grams = 5%.
One gram equals 1,000 milligrams.
