Cups of Rice to Grams Conversion
1 cup long-grain white rice = 185g
Rice weight varies by type and grain length. Long-grain white rice weighs 185 grams per cup. Short-grain rice packs denser at 200 grams per cup. The difference comes from grain shape. Long grains like basmati and jasmine have more air gaps between them.
Most rice packages list a 1/4 cup (45g) serving of dry rice, which cooks to about 3/4 cup. But recipes rarely use quarter-cups. The conversions below cover whole cups for practical cooking.
How to Convert
Multiply cups by the rice type's weight per cup. Long-grain white: cups x 185 = grams. Short-grain white: cups x 200 = grams. Brown rice (any grain): cups x 190 = grams.
Example calculation: Your paella recipe needs 3 cups of short-grain rice. Multiply 3 x 200 = 600 grams. If buying rice by weight, get at least 650g to account for what sticks to the package.
For cooked rice, the math changes completely. One cup of cooked white rice weighs about 195 grams. The rice absorbs its weight in water during cooking, but also expands in volume. This is why 1 cup dry rice yields about 3 cups cooked.
Common Mistakes
Confusing dry and cooked rice weights. Dry rice weighs 185-200g per cup. Cooked rice weighs 195g per cup but has triple the volume. A recipe for fried rice wants cooked rice. A pilaf recipe wants dry.
Using the wrong rice type's conversion. Arborio rice (200g/cup) is 8% heavier than basmati (185g/cup). That difference affects liquid ratios in risotto.
Measuring rice straight from a 20-pound bag without fluffing it first. Settled rice can pack 10-15 grams denser per cup. Stir the bag or container before scooping.
Pro Tips
Buy a rice cooker with cup markings. The included plastic cup holds exactly 180ml (3/4 of a US cup), which equals 150g of rice. Three rice-cooker cups = 450g = enough for 6-8 servings.
Store conversion ratios on your rice container. Write directly on the lid with a permanent marker: '1 cup = 185g' for long-grain, '1 cup = 200g' for short-grain. No more looking it up.
Weigh rice for consistency in special dishes. Sushi needs precise rice-to-vinegar ratios. Risotto needs exact rice-to-stock proportions. Volume measurements work fine for everyday steamed rice.
Ingredient-Specific Notes
Long-grain white rice
185g per cup. Includes basmati, jasmine, and standard long-grain. These rices stay separate when cooked because of their high amylose starch content (22-28%). Best for pilaf, biryani, and side dishes where you want distinct grains.
Short-grain white rice
200g per cup. Includes sushi rice and bomba rice. Higher amylopectin content (15-20% amylose) makes it stickier. Essential for sushi, paella, and rice pudding. The extra 15g per cup matters when scaling recipes.
Medium-grain white rice
195g per cup. Includes Arborio and Calrose. Falls between long and short grain in both weight and stickiness. Arborio's high starch content (20-21% amylose) creates risotto's creamy texture when stirred.
Brown rice (any type)
190g per cup regardless of grain length. The bran layer adds uniform weight across varieties. Requires 2.5 cups water per cup of rice versus 1.5-2 cups for white rice. The bran absorbs extra liquid.
Wild rice
160g per cup. Not actually rice but grass seeds. The long, thin shape leaves more air gaps. Needs 3 cups water per cup of wild rice and 45-60 minutes cooking time. Often mixed with brown rice at a 1:3 ratio.
Frequently Asked Questions
How many grams is 1 cup of uncooked rice?
185 grams for long-grain white rice like basmati or jasmine. Short-grain rice weighs 200 grams per cup. Brown rice averages 190 grams regardless of grain length. The 15-gram difference between long and short grain affects water ratios. Use 1.5 cups water for long-grain, 1.25 cups for short-grain per cup of rice.
How much does cooked rice weigh compared to dry?
Cooked rice weighs about the same per cup as dry rice (195g vs 185g) but triples in volume. One cup of dry long-grain rice (185g) becomes 3 cups of cooked rice (585g total). The rice absorbs 1.5-2 times its weight in water. A 45g serving of dry rice cooks to about 130g.
Should I measure rice by cups or weight?
Cups work fine for everyday cooking. Use weight for recipes where precision matters: sushi rice (2:2.2 ratio of rice to seasoned vinegar), risotto (1:3.5 ratio of rice to warm stock), or rice pudding (1:4 ratio of rice to milk). Restaurant kitchens weigh rice for consistent portioning. One serving = 75-90g dry rice.
Why do rice cookers use different cup sizes?
Rice cookers use a 180ml cup (3/4 US cup) based on the traditional Japanese go measurement. One rice-cooker cup holds 150g of rice. The water lines inside the pot match these smaller cups. Three rice-cooker cups equal 2.25 US cups or 450g of rice. Always use the cup that came with your cooker for accurate water levels.
Does rinsing rice change its weight?
Rinsing removes about 2-5g of starch per cup but doesn't significantly change the weight you should use in recipes. Wet rice appears heavier on a scale because of surface water. Drain thoroughly and shake the strainer before weighing. Some recipes specifically call for unwashed rice (risotto, rice pudding) because the extra starch serves a purpose.
