Quick Answer
This uncooked to cooked rice calculator uses the formula cooked rice equals dry rice times a rice-type yield factor, and dry rice equals cooked rice divided by that factor. It also estimates water needs, cook time, and serving count so you can plan both ingredients and finished portions.
Cooked rice is found by multiplying dry rice by the yield factor for that rice type, and the reverse conversion divides by the same factor.
Key Takeaways
- Rice yield depends on the variety, not just the starting amount.
- Dry-to-cooked and cooked-to-dry conversions use the same yield factor in reverse.
- Water need and cook time change by rice type.
- Cooked grams are much heavier than dry grams because of absorbed water.
- Serving estimates work best when paired with the recipe context.

Formula
Cooked rice = dry rice × yield factor; dry rice = cooked rice ÷ yield factor.
Where:
- R_c=Cooked rice amount(cups)
- R_d=Dry rice amount(cups)
- y=Yield factor by rice type
Worked Examples
1 cup dry jasmine rice
A common home-cooking batch for four people.
- 1Jasmine rice yields about 3 cups cooked per cup dry.
- 21 dry cup × 3 = 3 cups cooked rice.
- 3Water need = 1 × 1.5 = 1.5 cups water.
- 43 cooked cups ÷ 0.75 cup per serving = about 4 servings.
300 grams cooked basmati
Reverse-convert a cooked amount to the dry rice you should start with next time.
- 1Basmati cooked weight is about 163 grams per cooked cup.
- 2300 g ÷ 163 ≈ 1.84 cooked cups.
- 3Dry cups = 1.84 ÷ 3 ≈ 0.61 cups dry.
- 40.61 dry cups × 180 g per cup ≈ 110 g dry rice.
2 cups dry brown rice
Planning a larger batch of whole-grain rice.
- 1Brown rice yields about 3 cups cooked per cup dry.
- 22 dry cups × 3 = 6 cooked cups.
- 3Water need = 2 × 2.25 = 4.5 cups.
- 4Cook time stays near 40 minutes because time depends on rice type, not batch size.
Introduction
Rice expands differently depending on the variety, the amount of surface starch, and how much water the grain absorbs during cooking. This uncooked to cooked rice calculator uses rice-type yield factors to convert dry cups or grams into cooked portions, or to reverse the problem and tell you how much dry rice you need to produce a target cooked amount. It also estimates water needs, cook time, and side-dish serving count so the answer is useful for real kitchen planning.
What This Rice Calculator Does
The calculator translates between dry and cooked rice using realistic yield factors instead of one universal ratio. Long-grain white rice, brown rice, sushi rice, arborio, and wild blends all behave differently, so the same starting amount does not create the same finished volume.
The Rice Conversion Formula
The main formula is simple: cooked rice equals dry rice times a yield factor, and the reverse conversion divides by that factor. The hard part is choosing the right yield factor. This calculator stores that factor by rice type, along with typical water needs and an approximate cook time.
Why Rice Type Matters So Much
Long-grain white rice tends to fluff and separate, so one dry cup often yields around three cooked cups. Sushi rice and arborio absorb liquid differently and finish denser, so their yield factors are lower. Brown rice often needs more water and more time because the bran layer slows hydration.
How to Use the Calculator
Choose dry-to-cooked when you know how much uncooked rice you have on hand. Choose cooked-to-dry when you are meal-prepping and want to hit a finished serving target. Then pick cups or grams, select the rice type, and use the water and time outputs as a starting point for your cooking method.
Water Ratios and Cooking Time
Water need and cooking time are separate from the yield factor, but they help turn the conversion into a usable recipe. For example, white and jasmine rice often land near 1.5 to 1.75 cups of water per dry cup, while brown or wild blends need more. Cook time also varies widely, from about 15 minutes for basmati to 45 minutes for wild blends.
Understanding Serving Sizes
A side-dish serving of cooked rice is often around three-quarters of a cup. Main-dish rice bowls, fried-rice meals, or risotto portions may be larger. The serving output is therefore best used as a planning guide rather than a strict nutrition standard.
Common Conversion Mistakes
People frequently assume one cup dry always equals two cups cooked, but that shortcut can underfeed or overfeed a group depending on the rice. Another common mistake is confusing cooked-weight grams with dry-weight grams. A cooked gram is not interchangeable with a dry gram because water changes the mass dramatically.
Practical Tips for Better Rice Results
Rinse rice when the variety benefits from it, especially jasmine or sushi rice, to control excess starch. Rest the rice off heat before fluffing so moisture redistributes evenly. If you cook by absorption, keep the lid on; every steam leak changes the actual yield slightly.
When This Calculator Is Most Useful
Use it for weekly meal prep, restaurant batch planning, potluck scaling, and recipe adaptation. It is especially helpful when a recipe lists dry rice but you want cooked servings, or when leftovers are measured as cooked grams and you need to recreate the same batch later.

FAQs
How much cooked rice does 1 cup of dry rice make?
For many white rice varieties, 1 dry cup makes about 3 cooked cups, but the exact yield depends on the rice type.
Does brown rice expand the same as white rice?
Not exactly. Brown rice often uses more water and cooks longer, although its final volume can still land near three cooked cups per dry cup.
Can I convert cooked rice back to dry rice?
Yes. Divide the cooked amount by the rice-type yield factor to estimate how much dry rice you would need.
Why are grams different for dry and cooked rice?
Cooked rice includes absorbed water, so the mass is much larger than the starting dry grain mass.
Is 1 cup of cooked rice one serving?
Often that is closer to a generous serving. A common side-dish portion is around three-quarters of a cup cooked.
Does rinsing change the conversion?
Rinsing mainly changes surface starch, not the conversion math, although it can subtly change how separate the grains feel after cooking.
Can I use this for risotto rice?
Yes. Arborio is included, but remember that risotto often absorbs stock gradually and feels creamier than simple absorption-cooked rice.
