315 grams is 11.11129801 oz. The exact arithmetic is 315 × 0.03527396195 = 11.1112980141 ounces, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you. In fractional form it is about 11 7/64 oz — the version a set of kitchen scales actually shows.
315 g is 11.11 oz. In the kitchen that is about 2.52 US cups of plain flour at 125 g per cup, 1.57 cups of granulated sugar at 200 g, or 315 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 0.1113 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 315 that shortcut gives 11.25 ounces, off by 0.1387 ounces or about 1.25%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
