A fluid dram (also spelled fluid drachm) is a small unit of volume used primarily in pharmacy and medicine, particularly in the apothecaries' system of measurement. One US fluid dram equals exactly 3.69669 milliliters or one-eighth of a fluid ounce. The term derives from the Greek "drachme," an ancient unit of weight and volume. While largely replaced by metric measurements in modern medicine, fluid drams are still occasionally referenced in pharmaceutical contexts, historical medical texts, and some traditional compounding practices.
A milliliter is a standard unit of volume in the metric system, equal to one-thousandth of a liter or one cubic centimeter. It is the preferred unit for measuring liquid medications, laboratory samples, and small volumes in medical and scientific contexts worldwide. The milliliter's decimal relationship to other metric units makes calculations straightforward and reduces medication errors. In medical practice, milliliters have largely replaced traditional apothecary units like fluid drams, though understanding the conversion remains important for historical pharmaceutical formulations and some compounding applications.
One US fluid dram equals exactly 3.69669 milliliters. This is the standard conversion used in pharmaceutical calculations.
No, a fluid dram measures volume (3.69669 mL), while a dram (or drachm) measures weight (approximately 1.772 grams in the apothecaries' system). Always specify "fluid dram" when referring to volume.
Fluid drams are rarely used in modern medicine, which has largely adopted metric measurements. However, they may still appear in traditional compounding, veterinary medicine, and historical pharmaceutical references.
Multiply the number of fluid drams by 3.69669. For example, 10 fluid drams × 3.69669 = 36.9669 milliliters.
There are 8 fluid drams in 1 US fluid ounce. Since 1 fl oz = 29.5735 mL, this confirms: 8 × 3.69669 = 29.5735 mL.
The traditional symbol for fluid dram is "fl dr" or "fl ʒ" (using the apothecary symbol). In modern usage, "fl dr" is more common to avoid confusion.
