Stones
The stone is a unit of mass equal to exactly 14 pounds (approximately 6.35 kilograms), used almost exclusively in the United Kingdom and Ireland for expressing human body weight. Standardised by the Weights and Measures Act of 1835, the stone persists in British popular culture and medical contexts despite not being part of the SI system.
Micrograms
The microgram is a unit of mass equal to one millionth of a gram (10⁻⁹ kg) and represents the operational scale of endocrinology, toxicology, and trace-element analysis. Hormone concentrations in blood serum are typically measured in micrograms per decilitre, and environmental air quality regulations define acceptable concentrations of fine particulate matter in micrograms per cubic metre.
