How to convert grams to ounces
ounces = grams ÷ 28.349523125

A quick way to do it in your head
Divide by 30, then add a twentieth.
- 100 g: 3.33, plus 0.17 is 3.5 oz. The true answer is 3.53 oz.
- 250 g: 8.33, plus 0.42 is 8.75 oz. The true answer is 8.82 oz.
- 500 g: 16.67, plus 0.83 is 17.5 oz. The true answer is 17.64 oz.
An even quicker rule for the shops: 100 grams is three and a half ounces, and 450 grams is a pound.

Grams to cups depends on the ingredient
Grams measure weight and cups measure volume, so there is no single conversion between them. A cup of something dense weighs more than a cup of something light. These figures are for one US cup, and they are typical values: the real weight changes with the brand and with how firmly the cup is packed.
| Ingredient | One US cup weighs about | In ounces |
|---|---|---|
| Water or milk | 237 g | 8.4 oz |
| Granulated sugar | 200 g | 7.1 oz |
| Butter | 227 g | 8 oz |
| All-purpose flour | 125 g | 4.4 oz |
| Rolled oats | 90 g | 3.2 oz |
This is why baking recipes that give weights are more reliable than ones that give cups. If a recipe gives grams, weigh the ingredient, and convert to ounces only if your scale has no gram setting.
To go the other way, use oz to grams. For other units, see the unit converter.
