Ounces to Grams Converter

Convert ounces to grams instantly using the exact definition where one ounce is 28.349523125 grams. This weight conversion is a kitchen and shipping staple, needed whenever an American recipe, food label, or parcel weight is quoted in ounces but you want the metric grams used on most scales. Type any number of ounces and the gram value updates live as you type, carried to several decimals so it stays precise for baking, where small differences change the outcome. Keep in mind this is the standard avoirdupois ounce used for everyday weight, not the troy ounce reserved for gold and silver. Multiplying by 28.35 in your head is unreliable, so the tool keeps you exact. Everything runs free and instant in your browser, so your input stays private and the converter works offline once the page has loaded.
