About
Rolled oats are steamed and flattened oat groats that pack loosely, weighing only 3.35 ounces (95 g) per cup.
Rolled oats have a bulk density of roughly 25 pounds per cubic foot (0.4 g/mL) because their flat, irregular flakes trap empty space. A single US cup holds about 3.35 ounces (95 g), meaning a standard one-pound container requires nearly five cups of volume. Compared to denser grains like raw rice or packed flour, rolled oats take up significantly more room on the pantry shelf.
From Wikipedia
Rolled oats are a type of lightly processed whole-grain food. They are made from oat groats that have been dehusked and steamed, before being rolled into flat flakes under heavy rollers and then stabilized by being lightly toasted.
