The milligram is the unit of weight and the milligram is the unit of volume. There is a qualitative difference between them.

The milligram and milligram of the same object can be converted. To convert unit of volume into a unit of mass, it depends on the density of the substance. According to the formula: mass = volume * density.

For example, water, 1 mg of water is converted into milliliters, which means that the density of water is 1g/cm according to the density of water. , 1 mg =0.00 1 g,

So 0.00 1g/ 1g/cm? =0.00 1cm? =0.00 1ml, that is, 1 mg of water is 0.00 1 ml.
