198 g of brown rice is 1 cup, the same as white rice. The grains are the same size, so they weigh the same per cup, even though brown rice keeps its bran layer and takes almost twice as long to cook. The conversion is identical, but the cooking method is not, and that is where most brown rice mistakes happen.

How the measurement works
The figure on this page comes from King Arthur Baking, measured spooned and levelled. Whole-grain rice with the bran layer intact. Pilaf, bowls, stir-fries and side dishes.
All results on this page are approximate. Ingredient weights vary with brand, humidity, temperature and how firmly you pack the cup, so when a recipe has to work the first time, weigh the ingredient on a kitchen scale and use the numbers here as a guide.
Worked examples
Brown rice for a grain bowl
A grain bowl recipe serving four uses 396 g of brown rice, which is 2 cups uncooked. Rinse the rice, then simmer it in 5 cups of water for 40 to 45 minutes, until tender. Brown rice needs more water and more time than white rice, and it will not be ready in 20 minutes no matter how high you turn the heat up.
A brown rice pilaf for a dinner party
A pilaf recipe uses 198 g of brown rice, exactly 1 cup, toasted in butter with onion before the stock is added. Toasting the rice gives it a nutty flavour and helps the grains stay separate. The pilaf needs about 45 minutes to cook, and it should rest for ten minutes off the heat before serving.
Meal prep brown rice for the week
A meal prep plan calls for 792 g of brown rice, or 4 cups uncooked, cooked in a large pot and portioned into containers. That gives about 12 cups cooked. Brown rice keeps well in the fridge for five days, and it reheats better than white rice because the bran layer helps it hold its shape.
Practical guidance
Grains, seeds and similar dry goods should be spooned into the cup and levelled, without shaking or tapping the cup to settle them, which packs them down and inflates the weight. If the recipe calls for rinsed rice or oats, measure before rinsing: the water they absorb changes their weight, and a recipe written for dry weight will not work with wet grain. Store grains in airtight containers in a cool, dry place, and check for a stale or rancid smell before using older stock, because whole grains carry oils that go off faster than refined flour.
Scaling is straightforward once you know the cup weight. Doubling a recipe that calls for 198 g of brown rice means measuring 396 g, or 2 cups, and tripling it means 594 g, or 3 cups. Halving is just as easy: half a cup is 99 g. The key is to scale every ingredient by the same factor, because changing one ingredient without changing the others throws the recipe out of balance. A cake scaled by half still needs half the flour, half the sugar, half the butter and half the brown rice, not just half of one of them. If you are scaling a recipe by an awkward factor, like two thirds, weigh the brown rice rather than trying to measure two thirds of a cup in a jug, because the jug markings are not precise enough for fractions of a cup.
When should you weigh brown rice instead of measuring it? Whenever the recipe has to work the first time, and whenever the amount is large. A kitchen scale costs less than a single failed cake, and it removes the biggest source of variation in home cooking: the way ingredients pack into a cup or a spoon. Put the bowl on the scale, press tare, and add the brown rice until the display shows the number you need. There is nothing to wash afterwards except the bowl, and the result is the same every time. For small amounts, a level spoon is accurate enough, and for liquids, a jug is fine, but for anything where precision matters, the scale is the tool to reach for.
Storage. Airtight container, cool and dry, up to 6 months.
- Brown rice needs 2 1/2 cups of water per cup of rice.
- Soak for 30 minutes to shorten the cooking time.
- Store airtight and use within six months.
Frequently asked questions
Is brown rice the same weight as white rice per cup?
Yes. Both are 198 g per cup uncooked. The grains are the same size, and the bran layer on brown rice is thin enough that it does not change the weight in any measurable way.
Why does brown rice take longer to cook?
The bran layer is a barrier that slows water getting into the grain. Brown rice needs 40 to 45 minutes and about 2 1/2 cups of water per cup of rice, against 20 minutes and 2 cups of water for white rice.
How much cooked rice does 1 cup of dry brown rice make?
About 3 cups cooked, or roughly 600 g, the same as white rice. The volume triples, just as with white rice, though the cooked grains are chewier and nuttier.
Should I soak brown rice before cooking?
It helps. Soaking brown rice for 30 minutes before cooking shortens the cooking time by about ten minutes and gives a more even texture. It is not essential, but it is worth doing if you have the time.
How long does brown rice keep?
About six months in an airtight container in a cool, dry place, which is shorter than white rice because the bran contains oils that go rancid. Refrigerate it if you buy it in bulk, and check for a stale smell before using older stock.
Common mistakes to avoid
The most common mistake with grains and seeds is measuring them after rinsing, because the water they absorb changes their weight and a recipe written for dry weight will not work with wet grain. The second is shaking or tapping the cup to settle the contents, which packs them down and inflates the weight. The third is confusing cooked and uncooked measurements: a cup of dry rice becomes about three cups cooked, and a recipe that means one will not work with the other. The fourth mistake is storing grains in an open bag in a humid kitchen, where they absorb moisture and can develop mould or pantry moths. Finally, do not assume that all grains weigh the same per cup: oats are 89 g, quinoa is 177 g, and rice is 198 g, and swapping them cup for cup will change a recipe significantly.
