Glass Container Size Charts

With the many different measuring systems used by glass and plastic container manufacturers, it can be daunting trying to determine if a 2 drams container holds more or less than a 5 milliliter one. To make things less confusing, we have compiled some charts that not only explain the different measuring systems used by glass container manufacturers, but will hopefully help you be able to determine exactly how much liquid each container will hold.

Glass Measuring Systems Defined

  • Millileter (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/Imperial measurement system to measure units of liquid volume. One fluid ounce is equal to 1/8 of a cup, or 29.574 milliliters.
