Calories in 1 Cup of Cooked Rice, Pasta and Oats

By NYUS Inc. · Published 27 October 2026

General information: This article is information about food data. No dietitian or doctor has reviewed it, and it is not a substitute for their advice.
Disclosure: NYUS Inc. publishes this guide and makes the NYUS app, which is mentioned once near the end. The numbers below do not depend on it.

A plate of rice, a bowl of pasta, a pack of noodles, a morning bowl of oats: cooked grains are measured by the cup or the bowl, but calorie lists give them per 100 g, and cooked weight is not raw weight. This guide gives the calories per 100 g for six cooked grain and pasta records from USDA FoodData Central, then turns them into one cup and two cups using the cup weight USDA itself prints on each record, so none of the cup weights is our guess. The figures are for the plain cooked foods the records describe, not for a dish with oil, ghee, sauce, vegetables or milk.

The short answer

By the USDA records below, one cup of cooked white long-grain rice (158 g) is about 205 kcal and one cup of cooked brown rice (202 g) about 248 kcal. A cup of cooked spaghetti (124 g, not packed) is about 196 kcal, a cup of cooked egg noodles (160 g) about 221 kcal, a cup of cooked quinoa (185 g) about 222 kcal and a cup of oats cooked with water (234 g) about 166 kcal. Our reading: brown rice is lower than white per 100 g (123 against 130 kcal) but higher per cup, because USDA's cup of cooked brown rice weighs 202 g and its cup of white rice 158 g, so it is the weight in the cup that decides the calories.

Calories per 100 g and per cup

Indian lab values (IFCT 2017) do not cover these foods as cooked: Table 1 gives raw grains and flours per 100 g edible portion, as our raw rice, atta and dal guide shows, and has no cooked, boiled or prepared row that we found. So every row here is a USDA FoodData Central SR Legacy reference value, and the kcal per 100 g is the Energy figure printed on each record. Cooked weight is not raw weight: cooked rice, pasta and oats have taken up water, which is why the cooked white rice row below (130 kcal per 100 g) is far under the IFCT raw milled rice row (A015, 356 kcal per 100 g), and the two sets of rows should not be mixed. Every cup weight is the household portion USDA prints on that record page; we add no weights of our own. A US cup is about 240 ml and a katori is usually a smaller bowl, so the records give no katori weight: weigh your own cooked portion and scale from the table. USDA gives several cup weights for pasta, depending on the shape and on whether it is packed, so the table shows spaghetti and penne. Each figure is the grams times the kcal per 100 g in the table, divided by 100, rounded to the nearest kcal. The rows are US reference foods, not Indian brands or a particular recipe.

Frequently asked questions

How many calories are in a cup of cooked white rice?

The USDA FoodData Central SR Legacy record 168878 (Rice, white, long-grain, regular, enriched, cooked) prints 130 kcal per 100 g and lists 1 cup as 158 g, so a cup is about 205 kcal by our arithmetic. This is cooked rice: 100 g of cooked rice is not 100 g of raw rice, because the grains take up water. A katori is a smaller bowl than a US cup, so weigh your cooked portion and scale.

Is cooked brown rice lower in calories than white rice?

Per 100 g, yes in these records: USDA 169704 (Rice, brown, long-grain, cooked) prints 123 kcal against 130 for white rice (168878). Per cup it is the other way round, because USDA lists a cup of cooked brown rice as 202 g and a cup of white rice as 158 g: about 248 kcal against about 205 kcal by our arithmetic. At the same 200 g it is about 246 against 260 kcal.

How many calories are in a cup of cooked pasta or noodles?

USDA SR Legacy 169737 (Pasta, cooked, enriched, without added salt) prints 158 kcal per 100 g, and the weight of a cup depends on the shape: 124 g for spaghetti not packed (about 196 kcal), 151 g packed (about 239 kcal) and 107 g for penne (about 169 kcal). USDA 169732 (Noodles, egg, enriched, cooked) prints 138 kcal per 100 g and lists a cup as 160 g, about 221 kcal. These are USDA reference rows, not an instant-noodle packet.

How many calories are in a cup of cooked oats or quinoa?

USDA SR Legacy 173905 (Cereals, oats, regular and quick, unenriched, cooked with water, without salt) prints 71 kcal per 100 g and lists 1 cup as 234 g, about 166 kcal; its 0.75 cup of 175 g is about 124 kcal. USDA 168917 (Quinoa, cooked) prints 120 kcal per 100 g and lists 1 cup as 185 g, about 222 kcal. Oats made with milk, sugar or ghee are not the water row.

Does IFCT 2017 have cooked rice, pasta, noodles or oats?

Not in Table 1 that we found. IFCT 2017 Table 1 gives raw grains and flours, such as rice, wheat and quinoa, per 100 g edible portion, and no cooked, boiled or prepared rows, so every row on this page is a USDA FoodData Central SR Legacy record and the table says so.

Can I log a cup of rice or a bowl of pasta in NYUS?

NYUS is our app. You log foods yourself by searching 8,900+ Indian and global foods or by barcode; weigh your cooked portion for the best match. NYUS is in early access on Android: 30-day free trial, then plans from ₹499 for one month, paid once with no auto-renewal, no card needed to start.
