it depends on the density
-------------------------------------------------
Millilitre is a unit of volume and milligram is a unit of mass; they are not compatible.
The volume is the ratio mass/density.
So if you want to know the answer looking for first to this density.
No answer is possible because grams are mass and liters are volume. You must stipulate a material (or at least a density) to get an answer.
If the substance were water with a density of 1 then:
1000 mg (of water density 1) are in 1 ml
A milliliter (ml) is a unit of volume whereas a milligram (mg) is a unit of mass. In order to answer this question you would need to specify the substance as the answer will vary by the substance density.
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.
Some people still believe that there is a conversion in relation to water but that is only approximately true. Until 1964 a litre was defined as the volume of one kilogram of pure water at 4 deg Celsius and at a pressure of 760 millilitres of Mercury. With that definition 1 milligram of water (under those conditions) would have occupied 1 ml. But that definition of a litre was abandoned in favour of 1 litre =1000 cubic centimetres.

Milligrams versus millilitersOne milliliter of water weighs one gram. There are 1000 milligrams in one gram.One milliliter of other substances will weigh more or less, depending upon their densities. A millilter of gasoline, for example, weighs less, and a milliliter of mercury weighs more -- WAY more. (No pun intended.)Milligram is a unit of mass; milliliter is a unit of volume. You can't directly convert the two. If you know the density of a substance, you can say, for example, "1 milliliter of water has a mass of 1 gram (1000 milligrams)", or "1 milliliter of lead has a mass of about 11 gram".

This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.

Milligrams measure weight and milliliters measure volume, so it depends on the density of the measured thing.
I think what you mean to ask is how many milliliters (ml) are in a teaspoon, there are 5ml per teaspoon. Milligrams refers to the concentration of the medication as in how many milligrams per milliliter and that will vary from medication to medication

There are 50 grams in one milliliter and 1000 milligrams in one liter, so there are 50,000 milligrams in 50 grams.
A milligram is a unit of mass, a milliliter is a unit of volume. These two are incomparable.
The bottle will state how many milligrams there are per milliliter. The instructions included with the bottle will say how many milligrams per kg are needed for the species of animal to be treated. With that info you can calculate the number of milligrams you will be administering.
