Centimetres is a unit of length/distance and not a unit of weight/mass.
One cubic centimeter of water weighs one gram. Also note that a cubic centimeter is equal to one milliliter. __ NOTE__ All substances have different densities. The weight of a cubic centimeter depends on what one is weighing. 1 cubic centimeter of lead, for example, weighs 11.34  grams - but a litre of hydrogen (1,000 cc) weighs only 0.08988 grams.
One cubic centimeter (cc) of lead weighs approximately 11.34 grams.
One cubic centimeter (cc) of salt typically weighs about 2.16 grams.
Unfortunately, you also need to know what the substance is to find out how much each cubic centimeter weighs. However, 1 cubic centimeter of water weighs 1 gram. Thus 1000 cubic centimeters of water weighs 1 Kilogram.
1 milliliter or 1 cubic centimeter of pure water weighs 1 gram, or has the mass of 1 gram.
It means that is weighs 3.3 grams per centimeter cubed.
One liter of water weighs one kilogram. One kilogram is 1,000 grams. One liter is 1,000 cubic centimeters (a.k.a. "cc" or "ml") So: One cc weighs one gram. Isn't the metric system wonderful?
No, one centimeter is not equal to an inch. One inch is equivalent to 2.54 centimeters.
Density is a measure of how much mass is contained in a given volume. For example, the density of water is about 1 gram per cubic centimeter, which means that one cubic centimeter of water weighs 1 gram.
One cubic centimeter equals one milliliter. == ==
a centimeter is longer than a milimeter. In fact there is 10 millimeters in just 1 centimeter!
