You can measure the mass of any object in grams. The mass of a paper clip is about 1 gram. The mass of the Earth is about 6,000,000,000,000,000,000,000,000,000 grams. The mass of an atom of carbon is about 0.000 000 000 000 000 000 000 001 gram.
If you were to put 1 milliliter of water in a test tube and find its mass, it would be exactly 1 gram. If something has a density of 9 g/ml, that means that for every 9 grams of the substance, it takes up 1 milliliter of space. The units are what they are due to the equation. Mass = grams = g.
