One is the unit of weight and the other is the unit of volume, which cannot be directly converted to each other. Only through the density of matter can they be related to each other.

For example, the density of water is per milliliter 1 gram (that is, per cubic centimeter 1 gram)?

100 ml water quality = 1 g per ml * 100 ml = 100 g?

1 kg = 1000 g？

1 g = 1000 mg？

1 mg = 1000 micrograms?

100 mg water = 100/ 1000 g water =0. 1 g water.
