How it works
The gram is metric; the ounce is imperial. One avoirdupois ounce is defined as 28.349523125 grams, so converting is a single division.
ounces = grams ÷ 28.3495
1 oz = 28.3495 g · 16 oz = 1 lb
1 oz = 28.3495 g · 16 oz = 1 lb
Worked example
100 grams equals 100 ÷ 28.3495 = 3.53 ounces.

Kitchen scales usually round to 1 g or 0.1 oz, so for baking it is more accurate to stay in grams than to convert a recipe to ounces.
Grams for common kitchen ingredients
Recipes that list cups can be converted to grams, and then to ounces, only by ingredient, because a cup of flour weighs far less than a cup of sugar. Typical values per US cup:
| Ingredient (1 US cup) | Grams | Ounces |
|---|---|---|
| All-purpose flour | 120 g | 4.23 oz |
| Granulated sugar | 200 g | 7.05 oz |
| Butter | 227 g | 8.01 oz |
| Rolled oats | 90 g | 3.17 oz |
| Water | 237 g | 8.36 oz |
Values vary with how the cup is filled; spooning flour into a cup and leveling it gives the figure above, while scooping packs in more.
