Recipes, postage and product weights cross here. The ounce meant is the avoirdupois ounce, exactly 28.349523125 g — not the troy ounce used for gold and silver, which is 31.103 g. Mixing the two overstates a precious-metal weight by about 10%, which is why bullion is always labelled troy explicitly.
