Convert Oat Flour measurements
Oat Flour Measurement Converter
Use the tool below to convert oat flour from the measurements in your recipe to the measurements that you need.
Oat flour is oats ground fine, mild and faintly of porridge, and gluten-free when the oats are certified as such. A metric cup holds 100 grams, 40 grams lighter than the same cup of plain flour, so a cup-for-cup swap leaves a batter wetter than the recipe intended. Pancakes, muffins and soft cookies carry it best, since none of them lean on gluten for structure.
Those 40 grams are the whole problem with scooping. Fill a cup with oat flour where the recipe wanted plain and the bake is more than a quarter short of flour with the liquid unchanged, which is how oat pancakes turn out thin and oat muffins stay damp in the middle. Grams settle it: 100 to a metric cup, 96 to a US cup.

Good to know about oat flour
- Oats carry no gluten of their own, but they are usually grown in rotation with wheat and milled on the same equipment, so oat flour is only safe for coeliac baking when the bag says certified gluten-free.
- Oat flour bakes come out crumblier than the wheat version and often need a binder such as xanthan gum to hold their shape.
Frequently Asked Questions
- Are oat flour and ground oats the same thing?
- Yes. Ground oats is another name for oat flour, so they are the same ingredient and measure identically. A cup of oat flour weighs 100 grams under either name, and every conversion on this page holds whichever name your recipe uses. Recipes swap the two freely, so you can follow either without changing quantities or weighing any differently.
- What is 0.25 cups of oat flour in tablespoons?
- 0.25 cups of oat flour is 4.17 tablespoons. This is the same for any ingredient, since cups and tablespoons are both volume units and do not depend on what you are measuring. One cup is about 16.67 tablespoons, so 0.5 cups is 8.33 tablespoons. Use the volume converter to switch between cups, tablespoons, teaspoons, and millilitres for any amount. Open the volume converter
- How many cups is 1 ounce of oat flour?
- 1 ounce of oat flour comes to 0.28 cups. Scaling is linear, so 2 ounces is 0.56 cups and 1/2 ounce is 0.14 cups. This is the direction you need when a recipe hands you a weight and you would rather not get the scales out. Type your own figure into the converter at the top of this page for anything in between.
- How much does a cup of oat flour weigh?
- 1 cup of oat flour in grams is 100 grams. The ratio is fixed, so 2 cups is 200 grams and half a cup is 50 grams. Weighing oat flour by the cup is the most common way to measure it for baking. See the full cup to grams chart for oat flour, or use the converter on this page for any other amount. 1 cup oat flour in grams
- How do you measure oat flour in cups?
- 100 grams of oat flour is 1 cup. The conversion scales in a straight line, so 200 grams is 2 cups and 50 grams is 0.5 cups. Grams to cups helps when a recipe gives a weight but you measure with cups. See the full grams to cups chart for oat flour for more amounts. 100g oat flour to cups
- How do you measure oat flour in tablespoons?
- 50 grams of oat flour is 8.33 tablespoons. The ratio is fixed, so 100 grams is 16.67 tablespoons and 25 grams is 4.17 tablespoons. Tablespoons are handy for smaller amounts when you would rather not get out the scales. See the full grams to tablespoons chart for oat flour for the common amounts. 50g oat flour to tablespoons

Related to Oat Flour
Plain Flour
Plain flour brings gluten that oat flour lacks, so the crumb holds together better but loses the gluten-free benefit. Oat flour is lighter per cup (100 g vs 140 g), so weigh rather than scoop and expect a slightly firmer, less crumbly bake. See our Plain Flour converter.
Almond Flour
Keeps the bake gluten-free while adding richness and moisture. Almond flour (96 g/cup) has no starch to set, so it works best in cookies, muffins, and dense cakes rather than anything needing a tall, airy rise. See our Almond Flour converter.
Almond Meal
Ground almonds are roughly 50 percent fat, so almond meal absorbs far less liquid than oat flour does. If you substitute almond meal for oat or regular flour, reduce the butter or oil by about a tablespoon per cup of flour to avoid your bake turning greasy. Both almond meal and oat flour weigh 100 g per metric cup, so they are a 1:1 swap for both weight and volume. See our Almond Meal converter.
Rolled Oats
Oat flour is rolled oats milled to a powder, so the two are close in weight (100 g vs 90 g per cup). Blitz rolled oats in a blender to make your own oat flour, or weigh the flour when a recipe needs the fine, ready-ground form. See our Rolled Oats converter.
Bread Flour
Bread flour sits at the top of the wheat protein range (around 12 to 14%) and oat flour has no gluten at all, so they do opposite jobs in a dough. A quarter of the flour in a yeasted loaf is about as much oat flour as it will take before the rise gives out. See our Bread Flour converter.
Cake Flour
Both bake soft, for opposite reasons: cake flour because its protein sits low (around 7 to 9%), oat flour because it carries no gluten-forming protein at all. A cup holds 130 g of cake flour against 100 g of oat flour, so the scales matter more than the scoop when you trade one for the other. See our Cake Flour converter.
Self Raising Flour
Self-raising flour arrives with its leavener already blended in and oat flour has none, so an oat-flour version of the same recipe needs baking powder stirred through before it will rise. The self-raising flour calculator gives the amount for any weight. See our Self Raising Flour converter.
