Q:

How many milliliters are in one milligram?

A:

Since milliliters measure volume and milligrams measure mass, it is necessary to know the density of the substance to convert between the two. The formula mass equals volume times density calculates the conversion.

For example, the density of water at around room temperature is approximately 1,000 kilograms per cubic meter. If a person wants to use the formula, the units must correspond. Kilograms per cubic meter are equivalent to grams per liter. One milliliter is 0.001 liters. After multiplying 0.001 by 1,000, the answer is 1. Liters multiplied by grams per liter become grams. One milliliter of water at a density of 1,000 kilograms per cubic meter is equal to 1 gram or 1,000 milligrams.

• A:

In order to convert milligrams to milliliters, one must know the density of the substance; if the density is measured in milligrams per milliliter, the milligrams of mass of the object being measured are divided by the density of the substance to determine the volume in millimeters. Because density is generally not listed in milligrams per milliliter, it is likely that some calculations must be done to convert the density into the appropriate units.

In the most common definition of the grain unit of measurement, there are 64.8 mg in 1 grain, so there are about 0.016 grains in 1 mg. This grain unit is also known as a troy grain, an avoirdupois grain and an apothecary's grain. The metric grain or jeweler's grain is used to indicate the weight of diamonds and pearls and 1 metric grain is ¼ carat or 50 mg.
