The question is meaningless. No such thing as a cubic gram.
Multiply grams per liter by 0.001 to get grams per milliliter.
55,360 grams per liter.
To convert grams per milliliter to grams per liter, multiply by 1000. Therefore, 1.56 grams per milliliter is equal to 1560 grams per liter.
To convert grams per cubic centimeter (g/cm^3) to milligrams per liter (mg/L), you need to multiply by 1000. This is because there are 1000 milligrams in a gram and 1000 cubic centimeters in a liter.
1 milligram per litre is 0.001 grams per litre. 1 gram per litre is 1000 milligrams per litre.
density
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.
Molarity
To convert from grams per cubic centimeter to grams per cubic inch, we need to know that there are approximately 16.39 cubic centimeters in a cubic inch. So, we can convert the density of platinum from grams per cubic centimeter to grams per cubic inch by multiplying by 16.39. The density of platinum per cubic inch would be 21.4g/cm3 x 16.39 = 350.646 g/in3.
Each milligram per liter = 1.0 × 10-9 kilograms per cubic centimeter. So, multiply milligrams per liter by 1.0 x 10-9 to get kg per cubic cm.
You multiply by the density. Density is usually given grams per milliliter or kilograms per liter or grams per cubic centimeter, which are all interchangeable. Multiply by the density and then multiply by 1000 if given in one of the above units.
