White rice:
grams to cups.
One cup of uncooked white rice weighs 185 g. Rice grains pack together moderately well — not as densely as salt or sugar, but much more efficiently than oats or flour. Rice is also one of the few ingredients where cooking dramatically changes the cup-to-gram relationship.

Uncooked vs cooked: completely different conversion figures
The 185 g/cup figure applies to dry, uncooked white rice. Cooked white rice absorbs water during cooking and approximately triples in volume — 1 cup of dry rice yields about 3 cups of cooked rice. By weight, 185 g of dry rice expands to approximately 400–450 g of cooked rice (depending on water ratio and variety). If a recipe calls for "1 cup of cooked rice," that is not the same as "1 cup of uncooked rice." In recipes like rice salads, stuffed peppers, or rice pudding, where the ingredient is added already cooked, 1 cup of cooked rice weighs approximately 165–180 g (it packs less densely when moist and fluffy).
Long-grain, medium-grain, and short-grain: density differences
Long-grain rice (such as basmati or jasmine) has elongated grains that pack slightly less efficiently than the rounder medium and short-grain varieties. Long-grain white rice typically weighs 180–190 g per cup. Medium-grain rice (used for risotto) and short-grain rice (used for sushi) are rounder and pack more densely, potentially reaching 195–200 g per cup. The 185 g/cup figure is a reliable average for long-grain white rice, the most commonly used variety in American cooking. For sushi or risotto recipes that specify a particular rice type, expect the cup weight to be slightly higher.
