Rice Cups to Grams: Cooked vs. Uncooked Rice Chart

How many grams are in a cup of rice?

Rice weight depends on whether it is dry or cooked and on the variety. In a USDA reference table, 1 cup of raw regular long-grain white rice is 185 g, while 1 cup of cooked rice of that type is 158 g.

Rice reference	Amount	Approximate weight
Regular long-grain white rice, raw	1 cup	185 g (6.53 oz)
Regular long-grain white rice, cooked	1 cup	158 g (5.57 oz)
Long-grain brown rice, cooked	1 cup	195 g (6.88 oz)
Long-grain white parboiled rice, cooked	1 cup	175 g (6.17 oz)

These are reference portions for named forms of rice. Different grains, packing, and cooking methods can change the weight.

Rice cups to grams: common white-rice amounts

The following conversions multiply the USDA reference weight by the measured cup fraction. They are rounded to the nearest gram.

Amount	Raw long-grain white rice	Cooked long-grain white rice
¼ cup	About 46 g	About 40 g
½ cup	About 93 g	About 79 g
¾ cup	About 139 g	About 119 g
1 cup	185 g	158 g
2 cups	370 g	316 g
3 cups	555 g	474 g

For a weighed amount, use a kitchen scale. A volume cup is less exact because the grains can settle or be packed differently.

Uncooked rice and cooked rice are different measurements

Do not treat one cup of uncooked rice as equal to one cup of cooked rice. Cooking adds water, so the volume and total cooked weight change. The USDA reference values 185 g per cup raw and 158 g per cup cooked describe two separate one-cup portions; they do not say that one cup raw turns into one cup cooked.

There is no single gram amount for the cooked result of every dry-rice measure. The final batch weight depends on the rice, water used, draining, and how much water remains after cooking. To get the exact weight for a recipe, weigh the rice in the form the recipe specifies.

For jasmine rice, use the package instructions or weigh your own portion. Grain type and how it sits in the measuring cup can make a generic cup estimate differ.

Rice servings in grams: frequently asked questions

What is one serving of cooked rice in grams?

“Serving” depends on the recipe, package label, or meal plan. As a measurement reference, USDA lists one cup of cooked regular long-grain white rice at 158 g. That is not a universal serving recommendation.

How many ounces are in a cup of cooked rice?

The 158 g USDA reference is about 5.57 ounces by weight. This does not mean 5.57 fluid ounces; grams and ounces here describe weight.

How many grams are in a quarter cup of cooked rice?

Using the same 158 g-per-cup reference, a quarter cup is about 40 g.

How much does one cup of dry white rice weigh?

The USDA reference is 185 g per cup for regular long-grain white rice, raw. Different kinds or measuring methods can produce a different result.

If an exact portion matters, weigh the rice cooked or uncooked according to the recipe rather than switching between the two forms.
