Micrograms (μg)
Definition
A microgram (μg or mcg) is a metric unit of mass equal to one millionth of a gram (0.000001 g) or one thousandth of a milligram.
History
The microgram became important in the 20th century with advances in analytical chemistry, pharmacology, and toxicology. The ability to measure such tiny quantities revolutionized drug dosing and environmental monitoring.
Current use
Micrograms are essential in pharmacology (certain medications dosed in mcg, such as thyroid hormones and fentanyl), nutritional labeling (vitamins like B12 and D), and environmental science (pollutant concentrations).
Drams (dr)
Definition
A dram (dr) is an imperial unit of mass equal to 1/16 of an ounce or approximately 1.7718 grams in the avoirdupois system.
History
The dram derives from the Greek 'drachma', an ancient coin and weight. It entered English measurement through the apothecaries' system and was later incorporated into the avoirdupois system with a different quantity.
Current use
Drams are rarely used today in everyday measurements. They may appear in some older pharmaceutical prescriptions, historical texts, and occasionally in traditional crafts and recipes.
