38 ounces is 1077.281879 g. The exact arithmetic is 38 × 28.34952313 = 1077.28187875 grams, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
1077.28 g is 38 oz. In the kitchen that is about 8.62 US cups of plain flour at 125 g per cup, 5.39 cups of granulated sugar at 200 g, or 1077.28 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 22.72 g short of 1100 g, so if you need a round figure to quote, 1100 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 38 that shortcut gives 1064 grams, off by 13.28 grams or about 1.23%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
