None, but if you meant centigrams, there are 497.6 of them.
4976mg = 497.6cg (10mg per centigram).*Centigrams x 10 = mg*Milligrams/10 = cg
4 976 milligrams = 497.6 centigrams

This question cannot be answered sensibly. A milligram is a measure of mass, with dimensions [M]. A centimetre is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
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.
