Uncooked to Cooked Rice Calculator
Use our uncooked to cooked rice calculator to estimate cooked rice from raw rice using a simple ratio. Includes common raw rice to cooked rice ratios, whether 1 cup of uncooked rice equals cooked, and tips for cooked rice calories.
Uncooked Rice to Cooked Rice Explained
Rice expands when cooked because it absorbs water. That means a small amount of uncooked (raw) rice becomes a much larger amount of cooked rice.
An uncooked to cooked rice calculator estimates how much cooked rice you’ll get from a given amount of raw rice using an expansion ratio.
The exact ratio depends on the rice type and cooking method, but many everyday recipes use a simple average ratio for quick planning.
Raw Rice to Cooked Rice Ratio
A simple way to estimate cooked rice is to multiply uncooked rice by a typical expansion factor.
A common planning estimate is ~3× by volume for many white rices, but it can vary.
Weight-based ratios vary with water absorption and cooking loss.
Uncooked to Cooked Rice Chart
Quick estimates using a common planning ratio. Actual yield varies by rice type and cooking method.
| Uncooked rice | Estimated cooked rice |
|---|---|
| 50 g | 125 g |
| 100 g | 250 g |
| 150 g | 375 g |
| 200 g | 500 g |
| 250 g | 625 g |
| 300 g | 750 g |
This chart assumes a 2.5× cooked yield by weight. Your calculator can use a different ratio if you prefer.

Frequently Asked Questions
Cooked rice is usually 2× to 3× the amount of uncooked rice, depending on rice type and cooking method. A simple estimate is cooked ≈ uncooked × 2.5 (by weight) or ≈ uncooked × 3 (by volume).
No. 1 cup of uncooked rice becomes multiple cups when cooked because it absorbs water. Many people estimate roughly 3 cups cooked from 1 cup uncooked (varies by rice type).
It’s an expansion factor that estimates cooked yield from uncooked rice. Ratios vary: some rices expand less, and some (like certain long-grain varieties) can expand more.
Calories come from the uncooked rice. Cooking mostly adds water, which increases weight/volume but not calories. For portioning, you can divide total calories of the uncooked rice by the final cooked weight to estimate calories per gram of cooked rice.
Differences come from rice variety, water ratio, cook time, rinsing, evaporation, and how dry/fluffy vs soft you cook it. The calculator is a planning estimate.
