Rice is often measured by cups in home cooking, but grams are more reliable when you want consistent portions or need to scale a recipe. One US cup of dry white rice is commonly estimated at about 185 grams.
This calculator is designed for dry uncooked rice. Cooked rice weighs much more per cup because it absorbs water, so dry rice and cooked rice should not be converted with the same value.
Quick Rice Conversion Reference
These common rice measurements are based on 1 cup dry uncooked white rice = 185g. Use them for quick recipe checks before using the full chart below.

How to Convert Rice Cups to Grams
To convert rice from cups to grams, multiply the number of cups by 185. This page uses 1 cup of rice = 185 grams, which is a practical average for everyday baking.
grams = cups x 185 For example, if a recipe calls for 2 cups of rice, the calculation is 2 x 185 = 370 grams. If it calls for 1/2 cup, the calculation is 0.5 x 185 = 93 grams.
How to Convert Rice Grams to Cups
To convert rice from grams to cups, divide the gram amount by 185. This is useful when a recipe gives metric measurements but you want an approximate cup measurement.
cups = grams / 185 For example, 100g of rice is 100 / 185 = 0.54 cups. This is close to 8.6 tablespoons. Grams are still more reliable than cups because small measuring differences can change the texture of the final recipe.
Why Rice Cup Weight Can Vary
Rice cup weight changes by variety, grain length, brand, and how the cup is filled. Long-grain white rice, basmati rice, jasmine rice, short-grain rice, and brown rice can sit differently in a measuring cup.
Dry rice is also very different from cooked rice. A cup of cooked rice contains absorbed water, so it weighs more but represents a smaller amount of dry grain. This calculator uses 185g per cup for dry uncooked white rice as a practical everyday reference.
How to Measure Rice Accurately
The most accurate way to measure rice is with a digital kitchen scale. Place your bowl or pot on the scale, tare it to zero, and add dry rice until you reach the gram amount needed.
If you use cups, fill the measuring cup evenly and level the top. Do not shake the cup aggressively because small grains can settle and add more rice than expected.
If your rice cooker uses its own measuring cup, remember that it may be smaller than a standard US cup. Rice cooker cups are often around 180 mL, so follow the cooker instructions when using its water lines.
Rice Cooking Notes
Dry rice expands as it cooks. A cup of dry rice usually makes several cups of cooked rice depending on the rice type and water ratio.
For consistent meal prep, weigh dry rice before cooking. This helps you repeat portion sizes and water ratios more accurately than scooping cooked rice after it absorbs water.
Rinsing rice before cooking can remove surface starch and improve texture for many recipes. Rinsing changes the surface moisture slightly, but the dry weight measurement is still the best starting point.
Dry Rice vs Cooked Rice
This calculator is for dry uncooked rice. Cooked rice is not the same because it has absorbed water during cooking.
If a recipe says 1 cup cooked rice, do not use the 185g dry rice value. A cup of cooked rice usually weighs less than the amount of dry rice needed to make it, depending on cooking method and moisture.
Brown rice, jasmine rice, basmati rice, and short-grain rice can have slightly different cup weights. For most everyday white rice conversions, 185g per dry cup is a useful estimate.

Brown rice can be close, but the exact cup weight may vary by grain type and brand. For best accuracy, weigh rice in grams.
Is a rice cooker cup the same as a US cup?
Not always. Many rice cooker cups are smaller than a standard US cup. Use the cup that came with the cooker when following cooker water lines.
Conclusion
For most everyday cooking, you can estimate dry uncooked white rice at 185 grams per US cup. That means 1/2 cup is about 93g, 1 cup is 185g, and 2 cups is 370g.
