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 Gram (g)
A metric unit of mass equal to one thousandth of a kilogram (0.001 kg). Grams are the everyday unit for cooking, nutrition labels, precious metals, pharmaceutical dosing, and chemistry. A US nickel weighs 5 grams; a standard paperclip about 1 gram. In international trade and laboratory work the gram provides a conveniently human scale between the milligram and the kilogram, which is why nutritional information worldwide is quoted per 100 grams.
