How to Convert a Miligram Into a Milliliter

Since the volume and mass of an object are key factors in any type of scientific or mathematical measurement, it is important to know how to convert between the two mediums. While it is standard practice to measure mass in grams and volume in liters, smaller objects need to be measured in milligrams and milliliters. With a measuring scale and a simple calculation, you can convert milligrams to milliliters.

- 1
  Find the mass of the object, in milligrams, by placing it on a measuring scale. If the measurement is in grams, multiply the result by 1,000 to get the equivalent amount in milligram units.
- 2
  Divide the mass of the object by its density. For example, a small rock weighing 5,000 milligrams -- with a density of 5 kilograms per meter cubed (kg/m^3) -- would result in the number 1,000.
- 3
  Divide the number found in Step 2 by 1,000 to obtain the volume of the substance in milliliter units (mL). For example, if you had an object with the number of 1,000 from the Step 2, your object would have a volume of 1 milliliter (1,000 / 1,000 = 1).
