One Ounce equals 28349523.13 Micrograms (1 oz = 28349523.13 ug). Ounce is used in US recipe ingredients and in food portion sizes. Microgram is used in vitamin labels (mcg).

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.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
