How many grams in a cup of long grain rice, uncooked?
One US cup of long grain rice, uncooked weighs 185 g.
Uncooked. Cooked rice roughly triples in weight, so the two are never interchangeable in a recipe.
Every amount a recipe asks for
| long grain rice, uncooked | In grams |
|---|---|
| ¼ cup | 46 g |
| ⅓ cup | 62 g |
| ½ cup | 93 g |
| ⅔ cup | 123 g |
| ¾ cup | 139 g |
| 1 cup | 185 g |
| 2 cups | 370 g |
Going the other way
If you have a weight and need cups — rounded to the quarter cup, because that is the finest division a cup set actually has:
| 50 g | ¼ cup |
| 100 g | ½ cup |
| 200 g | 1 cup |
| 250 g | 1 ¼ cups |
| 500 g | 2 ¾ cups |
| 1000 g | 5 ½ cups |
Which cup does your recipe mean?
“A cup” is four different volumes, so the weight above changes with the recipe's origin. Same long grain rice, uncooked, same cup measure, different answer:
| Cup | Volume | One cup weighs | Used in |
|---|---|---|---|
| US customary | 237 ml | 185 g | American recipes and measuring cups |
| US legal | 240 ml | 187 g | nutrition labels |
| Metric | 250 ml | 195 g | Australia, New Zealand, Canada |
| Imperial | 284 ml | 222 g | British recipes before roughly 1980 |

Or stop converting by hand
Paste any recipe into RecipeTables and the whole thing converts at once — every ingredient, in one table, with a Cups/Grams switch that remembers which you use. It converts what the author wrote rather than inventing a weight the recipe never gave.
Try it on the recipe you're reading, or read why a cup isn't a cup — four volumes, the 25% flour problem, and the Australian tablespoon that's a third too big.
