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 Ounce (oz)
An imperial unit of mass equal to 1/16 of a pound (approximately 28.35 grams). Ounces are the everyday small-mass unit in the US for food portions, boxing-glove weights, ingredient measurements in American cookbooks, and postal rates for small packages. The avoirdupois ounce used here is distinct from the troy ounce (~31.1 g) used exclusively for precious metals — a common source of confusion when comparing gold or silver quotes to grocery scales.
