Converting 320 grams gives 11.28766782 oz. One multiplication does it — 320 × 0.03527396195 = 11.2876678239 ounces — and because the factor is defined rather than measured, that answer will not drift over time.
320 g is 11.29 oz. In the kitchen that is about 2.56 US cups of plain flour at 125 g per cup, 1.6 cups of granulated sugar at 200 g, or 320 ml of water — because a millilitre of water weighs a gram, which is the only reason weight and volume line up at all here.
The result sits 0.2877 oz past 11 oz, so if you need a round figure to quote, 11 oz is the honest nearest one. Plenty of people do this in their head: divide by 28 instead of using the exact factor 0.03527396195. At 320 that shortcut gives 11.428571 ounces, off by 0.1409 ounces or about 1.25%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
