About the Ounces to Grams
Converting ounces to grams changes imperial weights into metric units. One ounce (avoirdupois) is legally standardized to 28.349523125 grams. Converting to grams provides granular precision that prevents measurement errors in cooking, medicine, laboratory experiments, and postage.
To convert ounces to grams, multiply the number of ounces by 28.35 (for general tasks) or 28.349523 for laboratory precision. 16 ounces equal 1 avoirdupois pound (453.592 grams). 8 ounces equal half a pound (226.8 grams).
Because grams are small, intuitive units (one paperclip weighs roughly one gram), measuring ingredients in grams eliminates the ambiguity of fractional ounces when following international recipes.
