About This Conversion
Grams to ounces is a kitchen conversion above all: metric recipes into imperial scales, or nutrition labels into portion sizes. One ounce is exactly 28.349523125 g, and rounding it to 28 introduces a 1.2 percent error that compounds across a recipe.
The critical distinction is that this is the avoirdupois ounce, a unit of mass. A fluid ounce is a unit of volume and the two are not related by any fixed factor: 1 fl oz of water weighs about 29.6 g, but 1 fl oz of flour weighs roughly 15 g.
