The question reveals a serious misunderstanding of the units involved. One gram equals 1000 milligrams, and one kilogram equals 1000 grams, so there are one million milligrams in a kilogram. This is true REGARDLESS of the substance and no matter what its density, bulk or otherwise. Knowing the density of a substance -- including soil -- will allow you to calculate its weight in grams, milligrams, kilograms -- whatever!! -- if you know how much of it you have, because density is defined as weight per unit volume. Problems arise, however, when you have mixed units. If you know that a certain substance has a density of five pounds per gallon, you'll have to do some math to calculate its weight in kilograms if you have, say, 100 liters of it. Similarly, if you know the density of a substance is five ounces per milliliter, you'll have to do a conversion to calculate its weight in tons if you have a cubic yard of it.
To convert milligrams per liter (mg/L) to milligrams per kilogram (mg/kg) for sand, you need to know the density of sand to account for the volume change. Once you have the density, you can multiply the mg/L value by 1000 (since 1 liter of water is approximately 1 kilogram) and divide by the density of sand to get the mg/kg value.
To convert milliliters (ml) to milligrams (mg) for a liquid, you need to know the density of the substance. Once you have the density, you can multiply the volume in milliliters by the density in milligrams per milliliter to get the mass in milligrams. Without the density, it's not possible to convert directly from ml to mg.
To convert milligrams to microliters, you would first need to know the density of the substance in question. Once you have the density, you can use the formula: volume (µL) = mass (mg) / density (mg/µL). Without knowing the density, you cannot accurately convert milligrams to microliters.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
It can't be done. Additional information. Your 15 milliliters is 15 milligrams of water, but there is no direct conversion for other substances because of their different densities. Milliliters is a measure of volume, and milligrams is a measure of mass (weight). This question is similar to the question, "How do you convert gallons to pounds?" A gallon of water weighs more than a gallon of gasoline, and way less than a gallon of liquid mercury. Do you see the problem? Unless you have a conversion factor for the substance or a density or specific gravity of that substance, you can't get there from here.

You cannot. Milligram (not miligram) and kilogram are measures of mass whereas a litre is a measure of volume. So mg per kg is a pure ratio - with no units whereas the second is a measure of density with units of mg per litre. You cannot convert from one to the other without additional information.
To convert milligrams (mg) to cups, you need to know the density of the substance in question. Since milligrams measure mass and cups measure volume, the conversion depends on the density of the substance. Without knowing the specific substance, it is not possible to accurately convert 1000 mg to cups.
To convert milligrams (mg) to teaspoons, you need to know the density of the substance you are working with. The density of the substance will determine how much volume is occupied by a certain mass. Without knowing the density, it is not possible to accurately convert 30 mg to teaspoons. If you provide the density of the substance, I can help you with the conversion.
You cannot directly convert between volume and weight. Before you do this, you need to know the density.
you need to know the density, then convert your kilogram answer into lbs (x2.2)

Milligrams is a unit of mass. Milliliters is a unit of volume. To convert between these units you must know the density of the substance.Density = mass / volume.
To convert milliliters (mL) to milligrams, we need to know the density of the substance in question. The number of milligrams in 355mL will vary depending on the substance.
