How to use this page
- Use this page's calculator for dry rice going into a recipe or pot, not for a cup scooped after cooking.
- The cooked row is a household-measure reference, not a yield formula. One raw cup does not become one cooked cup because cooking adds water and changes volume.
- If a package names a different variety or gives its own serving weight, prefer that product-specific label.
Boundary: Cooked cup weight varies with rice variety, rinsing, water ratio, cooking method, resting and how firmly the cup is filled. Do not infer nutrition or cooked yield from the two reference rows alone.

Why weigh white rice (uncooked) instead of measuring cups?
A cup measures volume, but recipes really care about how much white rice (uncooked) you add by weight. One US cup of white rice (uncooked) is taken as 185 g here, cited from USDA FoodData, and every conversion on this page routes through that figure. Volume-to-volume and weight-to-weight steps are exact, but the cup→gram crossing depends on product form and how the white rice (uncooked) is packed, so a kitchen scale is the reliable way to hit the same result every time.
