How Many Grams of Rice Are in a Cup
A standard cup of raw rice (240 ml) weighs between 185 and 200 grams, depending on the type of rice. If we’re talking about cooked rice, that same cup weighs between 150 and 195 grams because the grain absorbs water and changes density. Here are the exact figures so your recipe never fails.
Grams of rice in a cup by type
Not all rice weighs the same in a cup, even if the volume is identical. The shape of the grain and its density make the difference:
- Long-grain white rice (raw): 185 grams per cup
- Round-grain white rice (raw): 200 grams per cup
- Brown rice (raw): 190 grams per cup
- Basmati rice (raw): 180 grams per cup
- Sushi rice (raw): 195 grams per cup
The difference between 180 and 200 grams might seem small, but in recipes for several people it adds up quickly and affects the amount of water needed to cook it.
How much a cup of cooked rice weighs
Once rice is cooked, the weight per cup changes because the grain absorbs water during cooking. A cup of cooked white rice weighs approximately 195 grams, while cooked brown rice weighs around 200 grams due to its more compact texture. This difference is key if you’re calculating portions for a diet or a restaurant menu.
As a quick reference: a cup of raw rice (185-200 g) yields between 2.5 and 3 cups of cooked rice, since the volume almost triples as it absorbs water.
Why weight varies between scales and measuring cups
A measuring cup measures volume, not weight. This means that how you fill the cup — whether you pack the rice down or leave it loose — changes the final result in grams. Rice poured without pressing can weigh 10-15 grams less than rice packed with your hand or a spoon.
So if your recipe requires precision (as in professional cooking or savory baking), the most reliable way is to weigh the rice directly on a kitchen scale instead of relying on volume alone.
Rice cup to grams conversion: quick table
To cook without pulling out a calculator every time, save this reference table using raw long-grain white rice as a base:
- 1/4 cup = 46 grams
- 1/3 cup = 62 grams
- 1/2 cup = 92 grams
- 2/3 cup = 123 grams
- 3/4 cup = 139 grams
- 1 cup = 185 grams
- 2 cups = 370 grams
These numbers serve as a universal starting point, though you should always adjust slightly if you’re using basmati, brown, or round-grain rice according to the data in the previous section.
How to weigh rice without a scale
If you don’t have a scale at home, a standard kitchen measuring cup (240 ml) is your best ally. Fill the cup without pressing the rice down and level the surface with the back of a knife, just as you would with flour or sugar. This method gives you a reasonably accurate measurement, with a margin of error of just 5-10 grams compared to the actual weight on a scale.
If you need greater accuracy, especially for converting international recipes, it’s worth using a grams to ounces calculator, useful when the original recipe uses imperial units and you want to convert the result to grams or vice versa.
How much rice per person: practical calculation
The standard portion of raw rice per person for a main dish is 60-75 grams, which is roughly 1/3 of a cup. If rice is a side dish, the portion drops to 45-50 grams, or about a quarter cup.
- 2 people (main dish): 120-150 grams = about 2/3 cup
- 4 people (main dish): 240-300 grams = about 1.5 cups
- 6 people (side dish): 270-300 grams = about 1.5 cups
Differences between raw and cooked rice when measuring
Confusing raw rice with cooked rice is the most common mistake when following a recipe. A recipe that calls for “1 cup of rice” almost always refers to raw rice, unless stated otherwise. If you measure already-cooked rice thinking it’s raw, you’ll end up with much less food than expected, since cooked volume represents only a fraction of the final volume you’d get after full cooking.
To avoid this confusion, always check whether the recipe specifies “raw rice” or “cooked rice” before grabbing the measuring cup.
How to apply this conversion to other recipes
This type of cup-to-grams conversion isn’t exclusive to rice. Ingredients like flour, sugar, or oats have different densities and require their own reference tables. If you’re making desserts or bread, it’s useful to check how many grams of flour are in a cup, since flour has a much lower density than rice and the gram result varies quite a bit.
If you often follow American recipes, it’s also worth understanding the full process to convert an American recipe from cups to grams step by step, so you avoid calculation errors with any ingredient, not just rice.
Frequently asked questions
How many grams of rice are in a cup?
A cup of raw long-grain white rice weighs 185 grams. If it’s round-grain rice, the weight rises to 200 grams, and if it’s brown rice, it comes to around 190 grams per cup.
How much does a cup of cooked rice weigh?
A cup of cooked white rice weighs approximately 195 grams, while cooked brown rice weighs about 200 grams due to its denser texture after cooking.
How do I convert rice from cups to grams without a scale?
Fill a standard 240 ml measuring cup without pressing the rice down and level the surface with the back of a knife. This method gives a result with a margin of error of only 5-10 grams compared to the actual weight measured on a scale.
Why does raw rice weigh differently depending on the type?
The shape and density of the grain vary between varieties. Round-grain rice packs more tightly in the cup and can weigh up to 15 grams more than basmati rice, which has longer, thinner grains with more air space between them.
How much raw rice do I need for 4 people?
For a main dish, calculate between 240 and 300 grams of raw rice for 4 people, which is roughly 1.5 cups. If rice is a side dish, the amount drops to 180-200 grams.
