How to Convert 30 Milliliters to Grams
You can convert 30 milliliters to grams using a simple equation, provided you know the specific density of the item you have 30 milliliters of. Any measurement of volume carries with it a corresponding weight; however, different gases and liquids have specific densities that will affect their weight. The ratio of volume to weight, milliliters to grams in this instance, will vary according to the substance to be measured.

Write down the volume in milliliters (mL) of the substance you want to know the weight of in grams (g). In this instance, write down 30 since you are trying to discover the gram weight of 30 mL of a substance.
-
2
Using a specific density chart, locate the gram per milliliter ratio for your substance. For example, suppose you want to find the gram weight of 30 mL of water. Water has a ratio of 1 gram to 1 milliliter (1:1). Write down (1) below the number of milliliters (30) that you want to convert to grams.

3
Multiply the volume of your substance by the grams per milliliter of the specific density of the substance. In this instance, if you have 30 milliliters of water, you will multiply the volume (30) by the density (1).
-
4
The solution to your equation is the amount of gram weight in the volume of your substance. In the example, 30 milliliters of water multiplied by the density of water (1) will give you an answer of 30. Since this is an equation to convert milliliters to grams, the correct way to write the answer is 30 g (or grams).

Tips & Warnings
Since a cubic centimeter (cc) is equal to a millimeter (mL) in volume, you can use the same equation if your substance is measured in cubic centimeters to discover the weight in grams (g) of your substance.
Always know the exact nature of the substance before consulting the specific density chart. Mislabeling your substance will provide you with the wrong ratio to use in your equation.
