Baking recipes from American sources use ounces while most of the world measures ingredients in grams. Getting this conversion wrong can ruin a recipe, especially for precision-sensitive baking where a few grams of leavener makes a significant difference. One avoirdupois ounce equals approximately 28.35 grams. Enter your ounce value to get an exact gram equivalent, and use the result with confidence whether you are measuring flour, calculating nutritional information, or figuring out postage weights.
