Some units of cosmetics are milliliter and some are gram. How to convert milliliter into gram?

Gram is a unit of weight of solid. Milliliter is the volume unit of liquid. Both are a measure of how much cosmetics are. A formula is the conversion formula of the two: density = mass / volume. Simply say, if the density of this cream is lighter than water, then the cream 50g will be converted to less than 50ml, that is to say, these 50 grams are more than 50 milliliters.
