You are using a term for volume and term for weight. They are only equal when referencing water.
The answer is: there aren't any milliliters in a milligram. Milliliters is a liquid measurement, milligrams are a unit weight or potency.
5.5 ml of a 10mg/ml solution
380 milligram/liter of Zithromax is equal to 0.38 milligram/mL of Zithromax. It is impossible to convert mg to ml because milligrams measure mass and milliliters measure volume.
Only if you have pure water in mind, then: 1 milliliter of pure water weigh 1 gram or 1000 milligrams. 0.001 milliliters of pure water weigh 1 milligram. Forget syrup, oil, or cat medication. For that calculations you need the specific weight (density) of the material.
A milligram is a 1000th of a gram which relates to weight a millilitre is a 1000th of a litre which relates to volume so technically they are talking about different things.
A milligram is a measure of mass just like a kilogram, while a gallon is a measure of volume. You cannot directly equate mass to volume. Under some idealized conditions a milligram of water is one milliliter. A milliliter is a unit of volume. There are 204,412 milliliters in 54 U.S. gallons
There is one milligram in one milligram.
Here are some 'milli' words: Millipede Million Milligram Millimeter Millibar Millisecond Milliliters
The number of milliliters in 200mg will depend on the density or concentration of the substance. To convert milligrams to milliliters, you would typically need to know the density of the substance in question.
The volume of fish oil in milliliters per milligram can vary depending on the density of the fish oil. Generally, fish oil has a density of around 0.92 grams per milliliter, so 1 milligram of fish oil would be approximately 0.92 milliliters.
There are 1000 micrograms in a milligram.
