How many mg equals 1ml?

Answer 1

Density =mass/volume, since 1 gm of water equals 1ml with density being 1.0 we get 1ml = mass/density = 1000mg/1 = 1000mg. Any liquid other than water multiply by its specific gravity

Answer 2

Millimeters are used to measure volume and milligrams are used to measure weight. Therefore, in order to figure this out you will need to know the density of the object you are measuring.

Answer 3

It depends on the substance being measured. For water, 1 ml is equivalent to 1 mg. However, for other substances, the conversion factor may vary based on the density of the material.
