The units are incompatible.
40000 units of what? without some known value to give an equivalence betweem 'units' and mg this cannot be answered.
no
It depends on the substance. Mass (mg) and volume (cc) are different things and use different units.
It depends on 0.5 measured in what units. The number of 0.5 grams in 2 mg will be different from the number of 0.5 nanograms, for example.
50000 iu
In any specific gravity, two units of mass will always be identical. Therefore, 7.5 milligrams of one item will always equal to 7.5 milligrams of another.
Depends on what units you are talking about :)
1 mg is equal to 1000 mcg
15000 mg
Gr.ss= mg
