White Rice (uncooked): Grams to Cups
1 cup of white rice (uncooked) = 185 grams
One US cup of white rice (uncooked) weighs 185 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 195 grams. To convert any weight, divide the grams by the figure for your cup.
Uncooked long-grain white rice weighs 185 g per cup (USDA FoodData Central). King Arthur Baking's figure is 99 g per ½ cup, about 198 g per cup. One cup of dry rice cooks to roughly three cups.
Dry rice, cooked rice and why the numbers differ
Rice grains are dense and pour like sugar, so dry rice converts reliably: about 185 g per cup for long-grain white. Short- and medium-grain rice are plumper and pack a little heavier. Cooked white rice is lighter per cup — USDA lists 158 g — because the grains swell with water and no longer pack tightly.
As a rule, 1 cup (185 g) of dry long-grain white rice absorbs about 1½–2 cups of water and yields about 3 cups cooked. Brown rice needs more water and longer cooking.
Rice-cooker cups are not US cups
The cup that comes with most rice cookers holds 180 ml — one traditional Japanese gō — not the 236.6 ml US cup. A rice-cooker cup of dry white rice weighs about 140–150 g. Use the cooker's own cup with the cooker's own water lines.
Portions by weight
A common single serving of uncooked rice is about 45 g (¼ cup), which cooks to roughly ¾ cup. For a side dish for four, 185 g (1 cup) of dry long-grain rice is typical. Weighing dry rice rather than cooked rice gives a consistent portion, because cooked rice changes weight as it cools and loses moisture.
