Teaspoons of uncooked brown rice to grams runs on one number, 3.9583333 grams per teaspoon. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
Water is the yardstick: 1 mL of it weighs 1 g. Uncooked brown rice comes in at 0.80308 g per mL, or 80.31% of water, which is why a cup of it is 190 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
A level teaspoon of uncooked brown rice weighs 3.958 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 25.3% resolution on a single spoonful, which is why measuring spoons beat scales below about 5 g and lose to them above it. Three teaspoons make a tablespoon, so the same spoonful is 11.88 g if the recipe scales up.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.526% of a cup of uncooked brown rice, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.632 cups, and a 1 kg pack 5.263.
How the figure is arrived at: The bran layer left on the grain makes it slightly heavier per cup than white rice of the same variety.
The formula
teaspoons- The amount of uncooked brown rice you are converting, in teaspoons
3.95833333333- Grams per teaspoon for uncooked brown rice, from its density of 0.80308 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in teaspoons.
- It is multiplied by 3.95833333333, the grams-per-teaspoon figure for uncooked brown rice.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
3/4 tsp of uncooked brown rice in grams
Take 3/4 tsp of uncooked brown rice: 0.75 × 3.9583333 gives 2.96875 grams. Doubling the batch takes it to 5.9375 grams, because the relationship is a straight proportion once the density is known.
1 1/2 tsp of uncooked brown rice in grams
A recipe calling for 1 1/2 tsp of uncooked brown rice needs 5.9375 grams on the scale. The arithmetic is 1.5 × 3.9583333 = 5.9375, and halving the recipe halves the weight to 2.96875 grams.
4 tsp of uncooked brown rice in grams
Take 4 tsp of uncooked brown rice: 4 × 3.9583333 gives 15.8333 grams. Doubling the batch takes it to 31.6667 grams, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many grams are in 1 tsp of uncooked brown rice?
One teaspoon of uncooked brown rice is 3.9583333 grams. Half that quantity is 1.97917 grams and double it is 7.91667 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of uncooked brown rice not 236 g like water?
Because weight per cup depends on what is in the cup. Uncooked brown rice has a density of 0.80308 g per mL where water has 1.00, so a cup of it weighs 190 g rather than 236.6 g. That is a difference of 46.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of uncooked brown rice by roughly 20% — about 19 g either side of 190 g — because the bran layer left on the grain makes it slightly heavier per cup than white rice of the same variety. Weighing removes the question entirely.
Is a fluid ounce of uncooked brown rice the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of uncooked brown rice weighs 0.8378 oz, so the two readings differ by 16.2%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of uncooked brown rice would weigh 200.77 g instead of 190 g — 10.8 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
At this size the spoon wins. One teaspoon of uncooked brown rice is 3.958 g, and a scale reading to the nearest gram is working at 25.3% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How many teaspoons of uncooked brown rice is 500 g?
500 g of uncooked brown rice is 126.32 teaspoons — 0.252632 teaspoons to one gram, so 500 × 0.252632 = 126.32. Going that way is a division by 3.95833, or a multiplication by 0.252632 if you prefer.
