Milligrams
The milligram is a unit of mass equal to one thousandth of a gram (10⁻⁶ kg) and is the standard unit of dosage in pharmacology and clinical medicine. Drug doses, vitamin quantities, and mineral recommended daily allowances are routinely expressed in milligrams, where precision is critical: in many medications the therapeutic margin is narrow, making accurate measurement a matter of patient safety.
Grams
The gram is a unit of mass equal to one thousandth of a kilogram (10⁻³ kg) and is the standard unit for small masses in chemistry, pharmacy, food science, and nutrition. In the CGS system, the gram was the fundamental unit of mass. In nutrition, all macronutrients — carbohydrates, proteins, and fats — are quantified in grams per serving.
