g = oz × 28.3495Formula
g = μg ÷ 1000000A microgram is one-millionth of a gram — far below what any kitchen scale can measure but routine in pharmacology and clinical labs. Hormone panels, drug tests, and environmental contaminant screens all report results in micrograms. Converting to grams is needed when aggregating data or comparing against bulk material specifications that use metric units.
