Uncooked long-grain white rice weighs 185g per cup, a figure that becomes considerably less useful once the rice is cooked — cooked white rice absorbs water and roughly triples in volume, which is exactly why recipes distinguish so carefully between "1 cup uncooked rice" and "1 cup cooked rice"; they are not remotely the same amount of food.
Rice density varies more by grain type than most pantry staples: long-grain white rice's slender, elongated grains pack somewhat differently than short-grain or medium-grain rice, and brown rice (with its bran layer intact) has its own separate figure (190g/cup uncooked) reflecting that structural difference — this site keeps rice varieties on separate conversion pages rather than treating "rice" as one interchangeable ingredient.
For recipes that specify a cooked-rice yield rather than a starting dry quantity, the general rule of thumb is that 1 cup of uncooked long-grain white rice yields roughly 3 cups cooked — useful for reverse-engineering how much dry rice to start with when a recipe only tells you how much cooked rice it needs.
Uncooked white rice's cup weight (185g) roughly triples in volume once cooked with standard absorption-method water ratios — the milling process that produces white rice removes the bran and germ layers brown rice retains, which is also why white rice cooks faster and has a milder flavor than brown rice.
Rinsing white rice before cooking removes surface starch that would otherwise make the cooked rice gummier and stickier — a step some cuisines specifically skip (for a stickier sushi rice, for instance) and others insist on, depending on the texture the dish is aiming for.

Frequently asked questions
Does 1 cup of uncooked rice equal 1 cup of cooked rice?
No — cooked rice absorbs significant water during cooking and roughly triples in volume, so 1 cup of dry, uncooked rice yields close to 3 cups once cooked. Always check whether a recipe means uncooked or cooked rice before measuring.
Does brown rice weigh the same per cup as white rice?
Close but not identical — uncooked brown rice weighs slightly more (190g/cup) than uncooked white rice (185g/cup), reflecting its intact bran layer, which also gives it a longer cook time and different water absorption during cooking.
Why does this site treat different rice types as separate ingredients instead of one 'rice' entry?
Because grain type genuinely changes both density and cooking behavior enough that a single averaged figure would be misleading — long-grain white, brown, and other rice varieties each get their own sourced conversion figure.
Does rinsing rice before measuring change this conversion?
No — this figure is for dry, unrinsed rice measured straight from the bag; rinsing happens after measuring in nearly every recipe, so it doesn't affect the dry conversion figure itself.
Does jasmine rice weigh the same per cup as standard long-grain white rice?
Close enough to use this figure as a reliable estimate — jasmine is itself a long-grain variety, and the density difference from standard long-grain white rice is small enough not to matter for most recipe conversions.
