What is a Dram and a Microgram?
The dram (or drachm) can refer to several units. In the context of common weight conversion (Avoirdupois system), it is a unit of mass equal to 1/16 of an ounce or 1/256 of a pound. This Avoirdupois dram is approximately 1.7718 grams.
A microgram is a unit of mass in the metric system equal to one millionth (1/1,000,000) of a gram, or one thousandth (1/1,000) of a milligram. It is often denoted by the symbol µg.
Note: The Dram is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Microgram belongs to the metric (SI) system.
History of the Dram and Microgram
The term originates from the Greek drachma coin. It became a unit in multiple historical weight systems (Avoirdupois, Apothecaries', Troy). The Avoirdupois dram was used for general commodities.
The microgram is derived from the gram, a base unit in early metric systems defined in the late 18th century. The prefix "micro-" indicates a factor of 10⁻⁶.

Common Uses for drams
- Historical Measurement: Found in older texts and recipes.
- Ammunition Reloading: Powder charges are sometimes measured in dram equivalents (though grains are more common).
- Note: The fluid dram (fl dr) is a unit of volume in the Apothecaries' system, distinct from the Avoirdupois dram mass unit.
Common Uses for micrograms
- Medicine & Pharmaceuticals: Measuring dosages of potent medications and vitamins.
- Chemistry & Biology: Quantifying trace amounts of substances in experiments.
- Environmental Science: Measuring concentrations of pollutants or contaminants.
- Nutrition: Specifying amounts of trace minerals and vitamins in food.
