How many milligrams is in one cc?

Answer 1

Cubic centimetres measure capacity, milligrams measure weight. They are not readily equivalent. If you have one cubic centimetre of say pure water at 4 degrees centigrade, at the sea level, that will weigh 1,000 milligrams, i.e: 1 gram. If you have one cubic centimetre of say quick silver, its weight would be much larger.

Answer 2

Only if you have only pure water in mind, you can say: 360 cubic centimeters of pure water weigh 360 grams. To calculate for other materials you need to know its specific weight (density).

Answer 3

It depends on the density of the material. A milligram is a unit of mass and a cc (cubic centimeter) is a unit of volume. Different substances have different densities, for example a cc of iron has more mass than a cc of styrofoam. In the metric system, one cc of water is exactly one gram (1000 milligrams). It's also 1 milliLiter. They originally did this on purpose so that everyone could figure out the measurements using something common and abundant. Now they have different, more precise standards, but for everyday applications it still holds true. In the food industry, they have such a thing as "fluid ounces", which may cause confusion that volume and mass measurements are interchangeable, but "fluid ounces" are a really measure of volume.
