10 ounces is 283.4952313 g. The exact arithmetic is 10 × 28.34952313 = 283.49523125 grams, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
283.495 g is 10 oz. In the kitchen that is about 2.27 US cups of plain flour at 125 g per cup, 1.42 cups of granulated sugar at 200 g, or 283.495 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 3.495 g past 280 g, so if you need a round figure to quote, 280 g is the honest nearest one. Plenty of people do this in their head: multiply by 28 instead of using the exact factor 28.34952313. At 10 that shortcut gives 280 grams, off by 3.495 grams or about 1.23%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
