A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Spoon the flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more.
You can make it by blending rolled oats; 1 cup of rolled oats gives a little under 1 cup of oat flour.
Weights are for a level US cup (236.6 ml) and level spoons, from King Arthur Baking's ingredient weight chart. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of oat flour weighs about 92 g (3.2 oz). A 250 ml metric cup weighs about 97 g.
1 level tablespoon of oat flour is about 5.8 g, and 1 teaspoon is about 1.9 g.
100 g of oat flour is about 1.09 cups, or 17.4 tablespoons.
A cup measures volume, not weight. Oat Flour is full of air between the particles, so a cup weighs much less than a cup of water (92 g vs 237 g).
