| 1 metric cup (250 ml) | 94 g |
| ½ metric cup | 47 g |

A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Pour grains into the cup and level them off. Cooked grains are lightly packed.
Quick oats weigh the same. Steel-cut oats are denser, about 140 g per cup.
Also called: old-fashioned oats.
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 rolled oats weighs about 89 g (3.1 oz). A 250 ml metric cup weighs about 94 g.
1 level tablespoon of rolled oats is about 5.6 g, and 1 teaspoon is about 1.9 g.
100 g of rolled oats is about 1.12 cups, or 18 tablespoons.
A cup measures volume, not weight. Rolled Oats is full of air between the particles, so a cup weighs much less than a cup of water (89 g vs 237 g).
