Ounces (oz) to Milligrams (mg) Conversion
Ounces
The ounce (avoirdupois) is a unit of mass equal to exactly 28.349523125 grams, or one sixteenth of a pound, used in the United States and United Kingdom for food portions, postal weights, and product labelling. It must be distinguished from the troy ounce (31.1035 g), used exclusively for precious metals, and from the fluid ounce, which is a unit of volume.
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.
