100 grams of oat flour = 1.09 cups (1⅛ cup / 17.4 tbsp / 52.2 tsp)
Oat Flour has a density of approximately 92g per cup. Homemade (blended from oats) can run closer to 100g. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 90g | 0.98 | ⅞ | 15.7 | 47.0 |
| 95g | 1.03 | 1⅛ | 16.5 | 49.6 |
| 100g | 1.09 | 1⅛ | 17.4 | 52.2 |
| 110g | 1.20 | 1¼ | 19.1 | 57.4 |
| 120g | 1.30 | 1⅓ | 20.9 | 62.6 |
How the 100g Figure Is Calculated
100g divided by 92g (the weight of one cup of oat flour) equals 1.09 cups. Multiplying that by 16 gives 17.4 tablespoons, and by 48 gives 52.2 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Oat Flour is lighter than water, which weighs about 236g per cup. That's why 100g of oat flour takes up more volume (257ml) than the same weight of water would (100ml). For a side-by-side look at how other ingredients compare, see the 100 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 1.09 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 100g, that's 1⅛ metric cups or ⅞ imperial cups of oat flour, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 100g Up or Down
Doubling a recipe that calls for 100g of oat flour means weighing 200g, or measuring 2.17 cups if you're working by volume instead of weight. Halving it means 50g, or 0.54 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
Oat Flour vs. Other Flours
Within flours, density still varies by ingredient. At 100g, almond flour (96g per cup) measures 1⅛ cup, while coconut flour (112g per cup) measures ⅞ cup, compared to 1⅛ cup for oat flour. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where 100g of Oat Flour Fits in a Recipe
- Oat flour muffins typically use 120g (about 1¼ cups) per batch.
- Gluten-free banana bread often calls for 180g of oat flour.
- Oat flour pancakes usually need about 100g for four servings.
How to Measure It Accurately
Flours
Spoon the flour into the cup, then level it off with a straight edge. Never scoop directly from the bag — that packs it down and adds extra weight.
For exact results
Sifting before measuring lowers the weight per cup by adding air, so a recipe written for sifted flour will call for a slightly larger volume than one written for unsifted. Check whether your recipe specifies sifted flour before comparing it to a standard chart.

Frequently Asked Questions
What is 100 grams of oat flour in cups?+
100 grams of oat flour is 1.09 cups (1⅛ cup), or 17.4 tablespoons.
How do I measure 100 grams of oat flour without a scale?+
Use 1⅛ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 17.4 tablespoons instead.
Why is oat flour's gram-to-cup ratio different from other ingredients?+
Oat Flour weighs 92g per cup because of its own density. Homemade (blended from oats) can run closer to 100g.
Does a metric or imperial cup change this 100g conversion?+
Yes, slightly. 100g of oat flour is 1⅛ metric cups or ⅞ imperial cups, versus 1⅛ US cups, since each cup standard holds a different volume.
