Pour grains into the cup and level them off. Cooked grains are lightly packed.
Whole flakes. Crushed cornflakes are about 85–100 g per cup.
Weights are for a level US cup (236.6 ml) and level spoons, from USDA FoodData Central household measures. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of cornflakes weighs about 28 g (0.99 oz). A 250 ml metric cup weighs about 30 g.
1 level tablespoon of cornflakes is about 1.8 g, and 1 teaspoon is about 0.6 g.
100 g of cornflakes is about 3.57 cups, or 57.1 tablespoons.
A cup measures volume, not weight. Cornflakes is full of air between the particles, so a cup weighs much less than a cup of water (28 g vs 237 g).
