One tablespoon of brown rice weighs 12.4 g (spooned and levelled, King Arthur Baking). Brown rice is the whole grain — the bran layer is still on — so it is heavier per tablespoon than white rice would be at the same volume, and it takes twice as long to cook. The tablespoon figure matters when you are measuring a small amount of rice for a single serving, scaling a recipe, or working out how much uncooked rice you need for a given number of people. It also matters because brown rice expands so much in cooking: a tablespoon of dry rice becomes about three tablespoons cooked. All weights on this page are approximate; grain size varies slightly by variety, so verify with a scale when precision matters.
How much does 1 tablespoon of brown rice weigh?
One level tablespoon of brown rice weighs 12.4 g, spooned and levelled, according to King Arthur Baking. That is the headline number, but a single tablespoon is rarely the whole story — most recipes use several spoonfuls, or a fraction of a cup, so the table below gives the weights you will actually reach for, from a teaspoon up to a full cup. Every figure is derived from the same source value of 198 g per cup, so the whole table is consistent. Treat all of these as approximate: spooned and levelled is a technique, not a machine setting, and two cooks measuring the same ingredient can differ by a gram or two per spoonful. When the recipe matters, weigh the ingredient on a kitchen scale instead.
| Amount | Weight (approx.) |
| --- | --- |
| 1 teaspoon | 4.1 g |
| 1 tablespoon | 12.4 g |
| 2 tablespoons | 24.8 g |
| 3 tablespoons | 37.1 g |
| 1/4 cup (4 tbsp) | 49.5 g |
| 1/2 cup (8 tbsp) | 99 g |
| 3/4 cup (12 tbsp) | 148.5 g |
| 1 cup (16 tbsp) | 198 g |
A useful rule of thumb: there are 3 teaspoons in a tablespoon and 16 tablespoons in a cup, so you can move between any of these measures by multiplying or dividing. If a recipe calls for 2 teaspoons and you only have a tablespoon measure, that is two-thirds of a tablespoon — about 8.2 g. If a recipe calls for a quarter cup and you only have a tablespoon, that is 4 level tablespoons. Keep the tablespoons to grams converter open while you cook and you will never need to do the arithmetic in your head.
Worked examples
A single serving of brown rice
A single serving of brown rice is about 4 tablespoons of dry rice — roughly 50 g — which cooks up to about 150 g, or a cup of cooked rice. The tablespoon weight is what makes this calculation possible without a scale: four level tablespoons is a sensible portion for one person, and it is easy to remember. The ratio is the important part — brown rice absorbs about twice its weight in water, so 50 g of dry rice needs about 100 ml of water and 40 minutes of simmering. If you cook by the tablespoon instead of by weight, the same ratio applies: 4 tablespoons of rice to 8 tablespoons of water is not quite right, because water is measured by volume and rice by weight, so use a measuring jug for the water and the tablespoon only for the rice.
A rice bowl for four
A rice bowl dinner for four uses 2 cups of brown rice — 32 tablespoons, or about 396 g — cooked in 4 cups of water. The tablespoon weight is useful when you only have part of a bag left and need to know whether it is enough: a bag with 200 g left holds about 16 tablespoons, which is exactly 1 cup, or two servings. Weighing the rice also lets you plan the cooking time — brown rice needs 40 to 45 minutes, and starting with the right amount means the rice finishes at the same time as the rest of the meal instead of holding everything up.
A stuffed pepper filling
A stuffed pepper recipe uses 6 tablespoons of cooked brown rice per pepper, but the recipe lists the dry amount: 2 tablespoons of dry rice per pepper, or about 25 g, which cooks up to the 6 tablespoons needed. The tablespoon weight is the bridge between the dry and cooked figures, and it is where most stuffed-pepper recipes go wrong — people measure the rice cooked and end up with twice as much filling as the peppers can hold. Measuring 25 g of dry rice per pepper, cooking it, and then mixing it with the other filling ingredients gives exactly the right amount, with no waste.
How to measure a tablespoon of brown rice correctly
Brown rice is measured spooned and levelled, and the method is straightforward: spoon the rice into the tablespoon measure and level the top with a knife, without pressing down. Rice grains do not compress much, so the tablespoon weight is fairly consistent at 12.4 g, but long-grain and short-grain varieties differ slightly — short-grain brown rice is rounder and packs more tightly, weighing about 13 g per tablespoon, while long-grain is about 12 g. For amounts above a few tablespoons, weighing is better: tare the bowl, pour the rice in, and stop at the target. The King Arthur figure of 12.4 g per tablespoon is for uncooked long-grain brown rice. Rinse the rice before cooking to remove surface starch, which makes the grains less sticky, and measure the water by volume — brown rice needs about twice its volume in water, or about 2 cups of water per cup of rice.
When the weight matters most
Brown rice's tablespoon weight matters most for portion planning, because the grain triples in volume when cooked and it is easy to cook far too much. A tablespoon of dry brown rice becomes about 3 tablespoons cooked, so the difference between 4 tablespoons and 6 tablespoons dry is the difference between a sensible portion and a plateful. The weight also matters for meal prep: brown rice keeps for 5 days in the fridge and freezes well, so cooking a large batch by weight and portioning it into 150 g cooked servings is the efficient way to plan a week of lunches. And it matters for nutrition — a tablespoon of dry brown rice is about 45 calories, and the bran layer that makes it heavier than white rice is also what gives it more fibre and a lower glycaemic index. Knowing the gram weight turns a vague scoop into a portion you can plan around.
Common mistakes to avoid
The most common mistake is cooking brown rice like white rice and serving it after 20 minutes, when it is still hard in the middle. Brown rice needs 40 to 45 minutes, and no amount of extra water will speed it up. The second mistake is measuring cooked rice with the dry figure — a cup of cooked brown rice weighs about 195 g, not 198 g of dry rice, and the two are not interchangeable. The third mistake is not rinsing the rice: unrinsed brown rice cooks up sticky and gummy, while rinsed rice stays separate. Finally, do not store brown rice at room temperature for months — the bran layer contains oils that go rancid, and brown rice should be used within 6 months and stored in a cool, dry place, or in the fridge for longer keeping.
Frequently asked questions
How many grams is 1 tablespoon of brown rice?
One tablespoon of uncooked brown rice weighs 12.4 g, spooned and levelled, according to King Arthur Baking. One teaspoon weighs about 4.1 g. These are approximate weights — grain size varies slightly by variety, so weigh it for the most accurate result.
How many tablespoons of brown rice are in 100 g?
There are about 8 tablespoons in 100 g of brown rice (100 divided by 12.4 is 8.1). A standard 1 kg bag holds about 81 tablespoons, which is roughly 5 cups.
How much does brown rice expand when cooked?
Brown rice roughly triples in volume when cooked. One tablespoon of dry rice (12.4 g) becomes about 3 tablespoons cooked (about 37 g). One cup of dry brown rice (198 g) makes about 3 cups cooked.
Can I use brown rice instead of white rice?
Yes, 1:1 by weight or volume, but adjust the cooking time and water. Brown rice takes about twice as long to cook as white rice (40 to 45 minutes versus 20) and needs slightly more water. The result will be chewier and nuttier, with more fibre.
How long does brown rice last?
About 6 months in a cool, dry cupboard, sealed tightly. The bran layer contains oils that go rancid, so do not keep it as long as white rice. Refrigerate or freeze it for longer keeping, and discard it if it smells musty or bitter.
