There is no equivalence.
A milligram is a measure of mass. A millilitre is a measure of volume. The two measure different things and,according to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider a millilitre of air. How many milligrams? Next consider a millilitre of lead. How many milligrams?

There are 1164 milligrams of sodium in 3.00 grams of NaCl. This is because sodium accounts for about 39.3% of the mass of NaCl, so you would multiply 3.00g by 0.393 to find the mass of sodium in milligrams.

None, but if you meant centigrams, there are 497.6 of them.
