380 grams is 13.40410554 oz. The exact arithmetic is 380 × 0.03527396195 = 13.4041055408 ounces, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
380 g is 13.4 oz. In the kitchen that is about 3.04 US cups of plain flour at 125 g per cup, 1.9 cups of granulated sugar at 200 g, or 380 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 0.4041 oz past 13 oz, so if you need a round figure to quote, 13 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 380 that shortcut gives 13.571429 ounces, off by 0.1673 ounces or about 1.25%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
