This question cannot be answered sensibly. A millilitre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
It takes only a little mental effort to compare a ml of air and a ml of water to see that the two will have very different masses.
Grams and millilitres measure different things. The gram is a unit of weight (or mass), while the millilitre is a unit of volume. For example, my cat weights 2495 grams (5.5 pounds). I cannot pour my cat into a measuring cup to measure how many litres she is.
Litres measure volume of fluids (usually, but we also use those same measuring cups for flour, sugar, etc. when we cook).
In the metric system, one millilitre of pure water weighs one gram. (It is also worth noting that one millilitre is defined as one cubic centimetre.)
HoweverIf you know what substance you are measuring, you can use stoichiometry to find its mass. You need the molarity of the liquid and the Atomic Mass of the liquid.
The molarity is moles per litre, just multiply that by the amount of substance to get moles of the substance, then multiply that by the atomic mass (in grams per mole) to get the mass in grams. If you have a substance with multiple component elements, you will need the molecular formula of the substance, and compute each component separately with their own atomic masses multiplied by their own masses(found by first taking the percentage of substance) before adding together.
It's actually the other way around!! There is 1000 millograms in a gram.
That is 0.3 of a gram

Three grams would be equal to 3000 milligrams. One gram would equal 1000 milligrams. The metric prefix of 'milli' represents a factor of one thousandth.

500 milligrams is equal to .5 grams.

1 gram is equal to 981 dynes.
There are 453,592 milligrams in one pound.
