3 Cups of Rice in Grams
555 g in a US cup — and what that figure assumes
3 cups of uncooked white rice weighs 555 grams, measured in a US cup.
That figure comes from one number: a full US cup of uncooked white rice is 185 g. Everything else on this page is that number scaled.
This is dry, uncooked long-grain white rice, poured into the cup and levelled. Do not press it down.
Whose cup you mean changes the answer. A 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — is 5.7% larger than the 236.6 ml US cup, so three cups of uncooked white rice is 586 g there rather than 555 g.
3 cups of rice in each cup standard
| Cup standard | Size | Grams | Ounces |
|---|---|---|---|
| US customary | 236.6 ml | 555 g | 19.58 oz |
| Metric (UK, AU, NZ, CA) | 250 ml | 586 g | 20.69 oz |
| Imperial (older UK) | 284 ml | 667 g | 23.51 oz |
A recipe that just says "cups" is almost always American. If yours came from a British, Australian or New Zealand source, take the metric row — on a 555 g measure the gap is 31.5 g.
Halving and doubling rice
Recipes get scaled more often than they get followed exactly. These are the portions of uncooked white rice a cook actually reaches for, already weighed out.
| Cups | Grams | Ounces | Tablespoons |
|---|---|---|---|
| ¼ cup | 46.3 g | 1.63 oz | 4 |
| ⅓ cup | 61.7 g | 2.18 oz | 5.33 |
| ½ cup | 92.5 g | 3.26 oz | 8 |
| ⅔ cup | 123 g | 4.35 oz | 10.67 |
| ¾ cup | 139 g | 4.89 oz | 12 |
| 1 cup | 185 g | 6.53 oz | 16 |
| 1½ cups | 278 g | 9.79 oz | 24 |
| 2 cups | 370 g | 13.05 oz | 32 |
| 3 cups | 555 g | 19.58 oz | 48 |
3 cups of rice in other units
| Unit | Amount |
|---|---|
| Grams | 555 g |
| Ounces (weight) | 19.58 oz |
| Pounds | 1.224 lb |
| Tablespoons | 48 |
| Teaspoons | 144 |
| Millilitres (the space it fills) | 710 ml |
Rice roughly triples in volume as it cooks, so this figure is for the dry grain. Cooked rice is about 186 g per cup — nearly the same weight, but a very different amount of food.
3 cups of something else
The same cup holds a different weight of everything, because ingredients do not weigh the same for their size.
| Ingredient | Grams per US cup | 3 cups weighs |
|---|---|---|
| Flour | 125 g | 375 g |
| Sugar | 200 g | 600 g |
| Butter | 227 g | 681 g |
| Milk | 244 g | 732 g |
| Oats | 90 g | 270 g |
| Powdered Sugar | 120 g | 360 g |
Frequently asked questions
How many grams is 3 cups of rice?
3 cups of uncooked white rice is 555 grams in a US cup, based on 185 g per full cup. In a 250 ml metric cup it is 586 g.
Is that weighed or measured?
Measured, then weighed on a scale. This is dry, uncooked long-grain white rice, poured into the cup and levelled. Do not press it down. A scale skips the question, which is why recipes that care about the result give grams.
How many tablespoons is 3 cups of rice?
48 tablespoons, or 144 teaspoons — 11.56 g per tablespoon for uncooked white rice.
How many ounces is 3 cups of rice?
19.58 ounces by weight. That is not the same as fluid ounces — 3 cups is 24 US fluid ounces of space, whatever is filling it.
Why do different sites give different grams for 3 cups of rice?
Because a cup is a volume and the weight depends on how it was filled, and on whose cup. This site uses 185 g per US cup. Rice roughly triples in volume as it cooks, so this figure is for the dry grain. Cooked rice is about 186 g per cup — nearly the same weight, but a very different amount of food.
