There can be 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 water. How many milligrams?
The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
Many people believe that there is an exact conversion for pure water: that is not true. It is only an approximation and that has been the case since 1964 when the definition of the litre was changed.

How many 250 mg tablets are needed to make 50 ml if the concentration is to be 500 mg per 5 ml?
To make 50 ml of a solution with a concentration of 500 mg per 5 ml, you would need to calculate the total amount needed: 50 ml / 5 ml = 10 units of 5 ml that are needed. Since each unit of 5 ml requires 500 mg, you would need 10 units x 500 mg = 5000 mg. To find out how many 250 mg tablets are needed to make 5000 mg, you would divide 5000 mg by 250 mg per tablet, which equals 20 tablets needed.
250Mg liquid equals how many milliliter?
if water, 250 Mg = 250 megagrams (i'm not sure that's what you mean) 250 Mg (megagrams) = 250,000,000 ml 250 mg (milligram) = 0.25 ml 250 ug (micrograms) = 0.00025 ml
How many ml are in 250 mg?
That would depend upon the density, because mg is a unit of mass, while ml is a unit of volume.
How many ml of ampicillin will you administer if the order is 400 mg per dose and the available stock is a vial of powder contituted by 3.5 ml and the result is 250 mg of ampicillin in 1 ml?
It looks like the 3.5 ml may be extraneous information. If 1 ml yields 250 mg, then you need 400/250 = 1.6 ml, to get 400 mg.
How much is 250 ml in mg?
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
How many 250 mg tablets are needed to make 5 ml of a suspension if you want the concentration to be 500 mg per 5 ml?
Two
250 mg equals how many ml?
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.
How many ML will equal the 250 mg?
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.
How many tablespoons in 250 milligrams?
250 mL = about 8.5 US fluid ounces.
How many 250 mg tablets are needed to make 50 ml of suspension if you want the concentration to be 500 mg per 5 ml?
20 tablets are necessary.
Jane has been prescribed 800 mg of penicillin orally stock mixture has a stenght of 250 mg in 5 ml what volume of the drug does Jane require?
16 ml
How many ml in 60 mg of toradol?
There are 1 mL in 15 mg of Toradol. Therefore, 60 mg of Toradol would be equivalent to 4 mL.
