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).
