How many milligrams are in a cc?

Answer 1

A milligram is 1/1000th of a gram, and is a measure of mass or weight. A cc is a cubic centimeter (cm3), and is a measure of volume. We cannot convert weight to volume directly. We can only convert weight to volume if we know something else, like the density of a material, a volume of which we are trying to figure out the weight of. In the case of water, it weighs 1 gram per cc, so there would be 1,000 milligrams per cc of water (at STP). Density is the weight of a specific volume of a substance or material. Units like grams per cubic centimeter or pounds per cubic foot would be used to express it.

Answer 2

1cc of water has a weight of 1mg at standard temperature and pressure. Because a cubic centimeter (cc) is a unit of volume and a milligram (mg) is a unit of mass or weight, there is no direct conversion for substances other than pure water unless the specific gravity of the substance is taken into consideration.

Answer 3

It depends on the substance being measured. However, as a general rule, 1 milliliter (cc) of water weighs about 1000 milligrams.
