How Many Ounces Is 100 Grams of Flour?
100 grams of flour is also 3.53 ounces, because ounces measure weight just like grams do. The ingredient only matters when you convert grams to cups, which measure volume — 100 grams of flour is 0.8 cups, while 100 grams of sugar is 0.5 cups, even though both weigh 3.53 ounces.

100 Grams to Ounces in Everyday Use
100 grams is a round metric amount that shows up on food packaging, postal scales and recipes all over the world, and 3.53 ounces is its US customary equivalent. Remembering that 100 grams is roughly three and a half ounces makes it easy to sanity-check any recipe or parcel weight at a glance.
Why Grams Have Different Cup Values
Cups measure how much space an ingredient occupies, while grams measure how heavy that ingredient is. Different foods pack different amounts of mass into the same volume, which is why a conversion must always include an ingredient.
How to Measure More Accurately
For dry ingredients such as flour, spoon the ingredient into the cup and level it off, and do not press it firmly unless the recipe asks you to pack it. For baking, a digital kitchen scale is usually the simplest way to reproduce a gram measurement consistently.
US Cups vs Metric Cups
Our main conversions use a US customary cup of 236.588 ml. Other cup standards change the grams-per-cup value, so the calculator above adjusts the result when you switch standards.
| Cup Standard | 1 Cup Volume |
|---|---|
| US Customary | 236.588 ml |
