Cooked white rice weighs 195 grams per cup, a figure that only makes sense alongside uncooked white rice's separate 185g-per-cup entry, since the two aren't remotely proportional to each other — rice roughly triples in volume during cooking as it absorbs water, so a cup of cooked rice represents considerably less dry rice than the same cup measurement of uncooked rice would.
That distinction matters most in recipes and nutrition contexts where "a cup of rice" is ambiguous about which state is meant — a recipe specifying cooked rice as a side-dish yield is describing a very different quantity of actual dry rice purchased than one specifying uncooked rice as a starting ingredient, and mixing the two up leads to either far too much or far too little food.
Cooked rice is also one of the more genuinely food-safety-sensitive items in this site's pantry category, in sharp contrast to dry rice's multi-year shelf stability — cooked rice can harbor Bacillus cereus spores that survive cooking and multiply if the rice sits at room temperature too long, which is why this site's storage guidance treats cooked rice as perishable with a strict 4-6 day fridge window, not a pantry item.
Cooked white rice's cup weight (158g) roughly matches what a standard rice cooker or stovetop absorption method produces at typical water ratios — the same rice, measured dry before cooking, weighs closer to 185g per cup and roughly triples in volume once fully cooked, a conversion worth checking carefully since recipes sometimes specify "cups" without clarifying dry or cooked.
Long-grain, medium-grain, and short-grain white rice all cook to somewhat different final textures — long-grain stays fluffier and more separate, while short-grain (used in sushi rice and risotto-adjacent dishes) releases more starch and cooks up stickier, a real textural distinction beyond this shared weight figure.

Frequently asked questions
How much dry rice does 1 cup of cooked rice actually represent?
About a third of a cup, since rice roughly triples in volume as it soaks up water while cooking — so a cup of finished, cooked rice actually started life as a noticeably smaller scoop of the dry grain.
Why is cooked rice more of a food-safety concern than dry rice?
The specific worry is Bacillus cereus, a bacterium whose spores can ride out the boiling process unharmed and then wake up and multiply if the cooked rice sits around at room temperature too long — dry, uncooked rice simply doesn't have enough moisture present for that organism to get going, which is the whole reason dry rice keeps for years on a shelf while the cooked version only holds for days in the fridge.
How long can cooked rice safely sit out before refrigerating it?
Refrigerate it within about 1-2 hours of cooking, following standard perishable-food guidance — leaving cooked rice out longer than that raises real risk from Bacillus cereus toxin formation, which isn't reliably destroyed even by reheating.
Does reheating cooked rice thoroughly make it safe again if it's been left out too long?
Not necessarily — while reheating kills active bacteria, some bacterial toxins (including those associated with Bacillus cereus) are heat-stable and aren't destroyed by reheating, which is why prompt refrigeration after cooking matters more than reheating temperature alone.
Can cooked rice be frozen?
Yes — cooked rice freezes reasonably well for about 6 months, a genuinely useful option for meal-prepping rice in bulk, though its texture is slightly firmer on reheating than freshly cooked rice.
