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.
