**Converting 385 milliliters to grams requires knowledge of the liquid being measured, but if the liquid is pure water, the conversion is 1-to-1 making 385 milliliters 385 grams.**

If any other liquid besides water is being measured, the density of the liquid must be taken into account as milliliters is a unit of volume and grams is a unit of mass. Once the density of the liquid is known, however, the conversion is a matter of simple multiplication. Identify the density of the liquid in grams per milliliter and multiply that by the number of milliliters to get the result.
