3 Cups of Rice in Grams

Three cups of raw white rice weigh 555 grams

USDA FoodData Central measures a level cup of raw long-grain white rice at 185 g (record 168877), so three level cups come to 3 x 185 = 555 g. That is 555 / 28.3495 = 19.58 oz and 555 / 453.592 = 1.22 lb, a batch that runs a fifth past a pound. Split three ways, each cup is the familiar 185 g; split in half, 277.5 g a portion.

Three cups occupy 709.8 mL, and 555 g packed into that space works out to 555 / 709.8 = 0.78 g per mL, well under water at 1.00. Level each scoop with the back of a knife and the batch lands within a few grams of 555 g. Three heaped scoops can push it toward 585 g, and damp grains run a few grams under, a small error in a pot this size but a real one in a recipe that sets its water by weight.

Sources round differently. The USA Rice Federation guide puts a dry cup at about 7 oz for menu planning, so three of its rounded cups come to roughly 595 g, while the USDA measured 185 g a cup gives 555 g. The USDA measure is what nutrition math and this converter follow; USA Rice's rounding is built for food service counts.

The default batch sits in the results already: 555 g, 19.58 oz, 6 cups of water, 18 half cup servings. Change the menu for brown, sushi, medium grain or cooked rice, or key in your own number.

Brown, sushi and medium grain at three cups

Swapping the grain moves the total by up to 45 g. Brown long-grain raw carries the same 185 g a cup (record 169703), raw short-grain white is listed at 200 g (record 168931) and medium grain at 195 g (record 169760), so three cups run 555 g to 600 g.

Cooked, record 168878 measures 158 g to the cup of white, so 3 x 158 = 474 g, and record 169704 measures 202 g to the cup of brown, for 606 g. Weight did not vanish: the 555 g of dry rice is in there, now spread thin over nine cups and padded with absorbed water.

No jasmine row exists in the USDA SR Legacy tables. As an aromatic long grain it weighs like regular long grain, so jasmine's three cups are the same 555 g.

Three dry cups make nine cooked cups

Dry rice triples as it cooks, the rule USA Rice publishes, so 3 x 3 = 9 cups come out of this batch. In grams that is 9 x 158 = 1,422 g of cooked white rice, or 9 x 202 = 1,818 g of cooked brown, and it covers 18 half cup servings: dinner for a big table, or a week of lunches plus a dinner.

A ceiling exists here too, set by water: the batch holds 555 x (1 - 0.116) = 490.6 g of dry matter, and since cooked white rice runs 68.4 percent water, the pot can hold 490.6 / 0.316 = 1,552.5 g at most, or 1,552.5 / 158 = 9.83 cups. Budget for 9 and let the lid keep the steam.

At this size the pot itself is the constraint: nine cooked cups plus headroom needs something large and heavy, and a crowded pot foams over and throws off the ratio. Cookers that run smaller should take the batch in two passes of 1.5 cups, water ratio unchanged.

2,026 calories dry, 1,849 cooked

By record 168877 the batch runs 555 x 3.65 = 2,026 calories, and the carbohydrate comes to 555 x 0.7995 = 443.7 g. Switch to brown and it is 555 x 3.67 = 2,037 calories with 555 x 0.762 = 422.9 g, fiber taking the place of some starch.

Once cooked, a 158 g cup of white holds 205.4 calories, so the nine cups total 1,422 x 1.30 = 1,849. Brown comes to 1,818 x 1.23 = 2,236. A half cup serving of the white batch lands near 103 calories, and the batch holds 18 of them.

Meal prep math: five packed 1 cup containers take 5 x 158 = 790 g of the batch and 790 x 1.30 = 1,027 calories, leaving 1,422 - 790 = 632 g, about 4 cups, for dinner the same night.

What three cups of rice costs

A dollar a pound works out to 1.22 x 1.00 = $1.22 for the batch, since 555 g is 1.22 lb, or 1.22 / 9 = $0.14 per cooked cup. Aromatic rice at $2.00 a pound doubles both numbers: $2.45 for the batch, $0.27 a cup.

Bag size does more for the price than brand: the $5.00 5 lb bag (12.26 dry cups) covers 12.26 / 3 = 4.09 batches, so a cooked cup lands at 5 / (12.26 x 3) = $0.14, and the $9.00 10 lb sack (24.52 cups) takes it to 9 / (24.52 x 3) = $0.12.

Compare takeout: three cooked cups cost 3 x 0.14 = $0.42 at home by the rounded cup price, while restaurant sides run $3.75 and up, and the home batch made nine cups, not three.

Meal prep and leftovers from a three cup batch

The 1,422 g the batch cooks into covers a week of packed lunches: seven 1 cup containers take 7 x 158 = 1,106 g, which needs 7 / 3 = 2.33 dry cups, or 2.33 x 185 = 431 g of raw rice. Round up to 2.5 dry cups (462.5 g) and the pot has a little slack at the edges.

Storage follows USDA Food Safety and Inspection Service leftover guidance: get cooked rice chilled within 2 hours, eat it inside 3 to 4 days, and bring portions back to 165 °F. Frozen leftovers hold 2 to 3 months, so half of a three cup batch can go straight to the freezer on prep day and come out as a plain side later.

Pack portions only once the rice is cold, and expect day old grains to fry up separate where fresh ones would clump.

Grams back to cups around 555 g

To turn grams into cups, divide by the weight of one cup. Raw white or brown takes 185: 1,422 / 185 = 7.69 cups, 555 / 185 = 3 cups. Cooked white takes 158, so 474 g is 474 / 158 = 3 cups, and cooked brown takes 202, putting the same 474 g at 2.35 cups.

In the tool: 1,422 g in the grams box reads 7.69 cups raw, and on cooked white rice the same 1,422 g reads 9 cups.

Why rice weights differ between sources

Two trusted sources print two different numbers for the same cup. USDA FoodData Central measures long-grain white rice and lands on 185 g raw and 158 g cooked, while the USA Rice Federation guide rounds to about 7 oz (198 g) per dry cup and 8 oz per cooked cup for portion planning. The gap is rounding, not error: food service works in whole ounces, nutrition labels work in measured grams.

For a recipe that must come out the same every time, follow the measured numbers, because a scale removes the scoop variable. Where a recipe writer worked from the 7 oz cup, three cups means roughly 595 g, and the pot runs about 40 g heavier than the USDA-based 555 g, a gap a couple of tablespoons of water absorbs.

The figures on this page and in the converter above are the USDA measured values, current as of November 2026 in the SR Legacy tables. If a package label lists a serving weight, the label wins for that bag, since brands vary in grain length and milling.
