A pharmacist carefully measures one fluidram of medicine into a small bottle.
Definition
Noun: 1. A unit of liquid capacity in the apothecary system: A fluidram is a unit of volume equal to one eighth of a fluid ounce. It is primarily used in pharmacy and medicine for measuring liquid medicines. 2. A British imperial capacity measure: In the British imperial system, a fluidram is a unit of volume (for both liquid and dry measure) equal to 60 minims or approximately 3.5516 cubic centimeters.
Usage Examples
- Noun:
- The old recipe called for two fluidrams of the tincture.
- In the imperial system, a fluidram is a very small unit of volume.
Advanced Usage
- Historical Context: The term "fluidram" is derived from "drachm" or "dram," an ancient unit of weight. The "fluid" prefix distinguishes it as a measure of volume rather than mass. Its use is now largely historical or specialized.
- Abbreviation: It is often abbreviated as fl dr.
- System Specificity: It is crucial to specify whether one is referring to the US customary fluidram (1/8 US fl oz) or the imperial fluidram, as they differ slightly in volume.
Variants and Related Words
- Fluid dram: An alternative spelling for fluidram.
- Dram (or Drachm): While traditionally a unit of mass, in liquid measure it is synonymous with fluidram in some contexts.
- Minim: A smaller unit of volume; 60 minims equal 1 imperial fluidram.
- Fluid ounce: A larger unit; 8 fluidrams equal 1 fluid ounce.
Synonyms
- Liquid dram: A direct synonym emphasizing it is a measure for liquids.
Notes on Meaning
- Apothecary vs. Imperial: The first definition pertains specifically to the apothecaries' system used in pharmacy. The second definition is for the broader British imperial system. The values are very close but not always identical in all historical implementations.
- Obsolete Status: This unit is considered obsolete in modern scientific and most clinical contexts, having been replaced by metric units like milliliters (mL). One fluidram is approximately equal to 3.6967 mL in the US system and 3.5516 mL in the imperial system.
