One gram of uncooked white rice is 0.25945946 teaspoons, so converting grams of uncooked white rice to teaspoons means multiplying by 0.25945946. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Put next to water — 1 g per mL exactly — uncooked white rice measures 0.78195 g per mL. That ratio, 78.19%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A level teaspoon of uncooked white rice weighs 3.854 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 25.9% 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 11.56 g if the recipe scales up.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.541% of a cup of uncooked white rice, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.703 cups, and a 1 kg pack 5.405.
What the number depends on: Long grain, unrinsed and dry. It roughly triples in volume once cooked, so the dry cup is the measurement worth converting — a cup of cooked rice is a different quantity entirely.
The formula
grams- The amount of uncooked white rice you are converting, in grams
0.259459459459- Teaspoons per gram for uncooked white rice, from its density of 0.78195 g/mL
teaspoons- The equivalent quantity in teaspoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.259459459459, the teaspoons-per-gram figure for uncooked white rice.
- The result appears in teaspoons, with a second reading in mL beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of uncooked white rice in teaspoons
A recipe calling for 50 g of uncooked white rice needs 12.973 teaspoons on the scale. The arithmetic is 50 × 0.25945946 = 12.972973, and halving the recipe halves the weight to 6.48649 teaspoons.

Frequently asked questions
How many teaspoons are in 1 g of uncooked white rice?
One gram of uncooked white rice is 0.25945946 teaspoons. Half that quantity is 0.12973 teaspoons and double it is 0.518919 teaspoons, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of uncooked white rice not 236 g like water?
Because weight per cup depends on what is in the cup. Uncooked white rice has a density of 0.78195 g per mL where water has 1.00, so a cup of it weighs 185 g rather than 236.6 g. That is a difference of 51.6 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 white rice by roughly 20% — about 18.5 g either side of 185 g — because long grain, unrinsed and dry. Weighing removes the question entirely.
Is a fluid ounce of uncooked white 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 white rice weighs 0.8157 oz, so the two readings differ by 18.4%. 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 white rice would weigh 195.49 g instead of 185 g — 10.5 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 white rice is 3.854 g, and a scale reading to the nearest gram is working at 25.9% 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 much does 2 tsp of uncooked white rice weigh?
2 tsp of uncooked white rice comes to 7.7083 g, or 7.7083 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the teaspoons-to-grams page does it in the direction the question is usually asked.
