About Milligram (mg)
A metric unit of mass equal to one thousandth of a gram (0.001 g), or one millionth of a kilogram. Milligrams are the standard unit for pharmaceutical dosing (e.g., a 500 mg aspirin tablet), vitamin and supplement labeling, and trace analytical chemistry. Medication orders, nutritional micronutrient values (sodium, caffeine), and environmental pollutant concentrations are almost universally quoted in milligrams because the unit matches the scale at which active compounds act on the human body.
About Stone (st)
A British imperial unit of mass equal to 14 pounds (about 6.35 kilograms). The stone is still the everyday unit for personal body weight in the United Kingdom and Ireland — where people say "I weigh 12 stone" rather than 168 pounds or 76 kilograms. Officially abolished from UK commerce in 1985, the stone nonetheless remains cultural shorthand on British bathroom scales, medical charts, and casual conversation about weight. Equine and livestock weights in Britain are also still sometimes quoted in stones.
