Grains conversions
Oats and rice are measured dry and loose. Oats are light and bulky, so a pound fills about twice as many cups as a pound of rice.
A pound of white rice fills about 2.45 cups, while a pound of rolled oats fills about 5.04 cups.
Grains weight and volume compared
| Ingredient | Grams per cup | Ounces per cup | Cups per pound | Cups per 100 g |
|---|---|---|---|---|
| Rolled oats | 90 g | 3.17 oz | 5.04 | 1.11 |
| White rice | 185 g | 6.53 oz | 2.45 | 0.541 |
Measuring grains accurately
Measure grains dry and loose, and level without shaking the cup. Rice roughly triples in volume when cooked, so 1 cup dry makes about 3 cups cooked.
How to measure each one
- Rolled oats: Measure oats loose; pressing them down changes the amount significantly.
- White rice: Keep dry rice loose in the cup and level the surface.
Swapping one for another
When substituting within this group, swap by weight rather than by cup. For example, 1 cup of rolled oats weighs 90 g; the same weight of white rice is 0.486 cups. Matching the weight keeps the recipe balanced even though the volumes differ.
Buying and storing
Grains are sold by weight. An 18-ounce canister of rolled oats holds about 5½ to 6 cups dry, and a 2 lb bag of rice about 5 cups. Store both airtight; brown rice has more oil than white and keeps best in the fridge.
