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).
Stone (st)
Definition
A stone (st) is an imperial unit of mass equal to 14 pounds or approximately 6.35029 kilograms.
History
The stone has been used as a weight measure in England and Ireland since at least the 14th century. Different commodities historically used different stone weights; the 14-pound stone was standardized in 1835 by the British Weights and Measures Act.
Current use
Stones are primarily used in the United Kingdom and Ireland to express body weight (e.g., '11 stone 4 pounds'). They are not used in the United States or most other countries.
