To convert from mass (milligrams; mg) to volume (cubic centimeters; cc), you need to know the density of the liquid.

If we assume the density of your liquid is like water, then the conversion from ccs to grams is 1:1 because 1 gram of water is 1 cubic centimeter. CC is a unit of volume. It's one cubic centimeter and the same volume as 1 ml. But, each thing has its own density and you cannot know they are exact.

Milligrams, on the other hand, is a unit of weight. There's no clear conversion between the two because of the difference in the density of what you are converting.

If you are asking this because of a medication you are taking, don't try to do this by yourself. Contact your pharmacist and get your doseage right before you take it
