Grams to ounces is a kitchen and postage conversion above all else. The complication is not the arithmetic but the word 'ounce': the avoirdupois ounce used for weight, the fluid ounce used for volume, and the troy ounce used for precious metals are three different units that share a name.

Serious baking is done by weight because a cup of flour varies with how it was scooped. US recipes give ounces, most scales outside the US read grams, and 4 oz of flour is 113 g — a conversion done at every step of an imported recipe.
US labels give serving sizes in both grams and ounces, with the ounce figure rounded. A 28 g serving is printed as 1 oz even though 1 oz is 28.35 g, so the two numbers on the same label are not exactly equivalent.
US postal rates step at ounce boundaries while international scales read grams. A package at 100 g is 3.53 oz — over the 3 oz step, into the 4 oz band.
Brew ratios are published in grams worldwide, and US bags are sold in ounces. A 12 oz bag is 340 g, which at 18 g per cup is about 19 cups.

The avoirdupois ounce is 1/16 of a pound, making it exactly 28.349523125 grams. A troy ounce, used only for precious metals, is 31.1035 g — about 10% heavier. A US fluid ounce is not a mass unit at all; it is a volume of about 29.57 mL. A recipe calling for '8 oz of flour' means weight, while '8 oz of milk' in a US recipe almost always means fluid ounces, and the two are not interchangeable because flour is far less dense than water.
Kitchen scales read to 1 g or 0.1 oz, so one decimal place is the practical limit for cooking. Rounding 28.3495 to 28 introduces a 1.2% error, which is invisible in a stew and noticeable in bread or pastry where hydration ratios matter. For anything sold by weight commercially, the applicable legal metrology rules — not a general rounding convention — govern how the figure must be stated.
8 fl oz of water happens to weigh about 8 oz, which is where the confusion comes from — but 8 fl oz of flour weighs about 4.4 oz. The coincidence only holds for water.
Gold and silver are quoted in troy ounces of 31.1035 g. Applying the 28.35 g avoirdupois factor to a bullion weight understates it by about 10%.
For yeast, salt or spices, rounding 7 g to a quarter ounce and back can shift the amount by 10% or more. Weigh small ingredients in grams directly.
