About Milligram and Ounce

The milligram is one thousandth of a gram, or a millionth of a kilogram. Medication dosages and trace nutrient amounts are stated in milligrams. The ounce is one sixteenth of a pound, exactly 28.349523125 grams. US recipes, portion sizes, and postal rates use it for quantities a pound would state too coarsely. One Milligram equals 0.00003527396195 Ounces (1 mg = 0.00003527396195 oz). Milligram is used in medication dosages and in vitamin and supplement labels. Ounce is used in US recipe ingredients.

Precision and Rounding:Metric-imperial mass factors are exact (1 lb = 0.45359237 kg by the 1959 agreement), so precision is purely a display choice. One decimal place is enough for body weight and cooking; nutrition labeling, pharmacy, and lab work need the full factor before rounding.
