Uncooked Rice: Cups to Grams
Also called white rice or long grain rice.
One US cup (240 ml) of uncooked rice weighs 185 grams; half a cup weighs 92.5 grams. A quarter cup is 46.3 grams, a tablespoon is 11.6 grams and a teaspoon is 3.85 grams. These numbers are for uncooked rice only, because a cup measures volume, not weight.

Ounces here are ounces of weight (1 oz = 28.35 g), not fluid ounces. One US cup is 8 fluid ounces of volume whatever is in it, but what it weighs in ounces depends on the ingredient: a cup of uncooked rice weighs about 6.53 oz. Why these two are not the same. Decimals for thirds are rounded (1/3 cup is 0.333 cups), and each linked amount opens a page comparing every ingredient at that measure.

About measuring uncooked rice
Uncooked white rice is made of small, hard grains that settle closely, so one US cup weighs about 185 grams. The grains pack fairly consistently, which makes rice easier to measure by volume than powders. Weighing still helps when you are cooking precise ratios of rice to water, or scaling a recipe for a crowd. Note that rice roughly triples in volume once cooked, so a cup of dry rice yields around three cups cooked.
Dry rice roughly triples in volume when cooked, so one cup dry gives about three cups cooked.
How many grams is a cup of uncooked rice?
One US cup (240 ml) of uncooked rice weighs about 185 grams. Because a cup measures volume rather than weight, that figure is specific to uncooked rice and does not transfer to any other ingredient: the same cup holds 125 grams of all-purpose flour and 340 grams of honey.
- 1/4 cup of uncooked rice is about 46 grams
- 1/3 cup of uncooked rice is about 62 grams
- 1/2 cup of uncooked rice is about 93 grams
- 2/3 cup of uncooked rice is about 123 grams
- 3/4 cup of uncooked rice is about 139 grams
- 1 1/2 cups of uncooked rice is about 278 grams
- 2 cups of uncooked rice is about 370 grams
- 3 cups of uncooked rice is about 555 grams
Working the other way round, 100 grams of uncooked rice is about 0.541 cups, and 500 grams is about 2.7 cups.
Does it matter which cup my recipe means?
It does, though less than the ingredient itself. This page uses the US legal cup of 240 ml. An Australian metric cup is 250 ml, so a metric cup of uncooked rice comes to about 193 grams, and the old British imperial cup of 284.1 ml holds about 219 grams. See cup sizes by country for every standard side by side.
Frequently asked questions
How many grams is 1 cup of uncooked rice?
One US cup of uncooked white rice is about 185 grams. The small, hard grains settle closely, so rice is fairly dense.
How much cooked rice does a cup of dry rice make?
About three cups. Rice roughly triples in volume as it absorbs water, so plan your pot size accordingly.
Does brown rice weigh the same as white?
Nearly. Brown rice keeps its bran and can be a touch heavier per cup, but 185 grams is a reliable figure for both.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of uncooked rice. The 185 grams on this page follows the calibration the rest of the site is built on, with butter at 227 grams per cup, water at 240, all-purpose flour at 125 and granulated sugar at 200. Treat it as a good working figure rather than a cited one. If you have a better source, tell us and we will check it and credit you.
Published figures for the same ingredient vary between references anyway, because how an ingredient is packed changes what a cup of it weighs. Treat any cup figure as accurate to within a few percent, and weigh on a scale when a recipe is sensitive. Our full approach is on the methodology page.
