OZ to Grams Converter

Convert ounces to grams instantly using the exact definition where one ounce is 28.349523125 grams. This is a kitchen and shipping mainstay, needed whenever an American recipe, food label, or parcel weight is quoted in ounces but you need metric grams. 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 result. 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 not reliable, so the tool keeps you exact. It runs entirely in your browser, so the answer is instant, your input stays private, and it works offline once the page has loaded.
