Glass & Plastic Bottle Measuring Systems Definitions

  • Milliliter (ml): Milliliters are used in the metric measurement system to measure units of liquid volume. One milliliter is equal to one cubic centimeter or 1/1000 of a liter.
  • Dram (fl. dr.): Drams come from the old English apothecary system and are used to measure units of liquid volume. One dram is equal to 1/8 of an ounce, or 3.697 milliliters.
  • Ounce (fl. oz.): Fluid ounces are used in the Engish measurement system to measure units of liquid volume. One fluid ounce is equal to 1/8 of a cup, or 29.6 milliliters.
  • Drop: Actual drop sizes can vary depending on the thickness of the oil and the size of the dropper. For purposes of this chart we are using the pharmaceutical standard drop, 0.05 mililiters (approximate size of a drop of water.)
