A practical rice and water ratio scenario
For this example, use dry rice of 300 g, water-to-rice ratio of 1.5 ×, and extra water for evaporation of 30 g. These are starting values, so replace them with numbers that match your situation.
Dry rice: 25% lower
Change dry rice to 225 g while keeping the other example values the same.
Dry rice: 25% higher
Change dry rice to 375 g while keeping the other example values the same.

Quick answer
What does the Rice and water ratio calculate?
How much water is needed for the entered dry rice and ratio? This calculator uses dry rice, water-to-rice ratio, and extra water for evaporation to estimate water for the rice immediately in your browser.
With the values currently entered, the result is 17 oz — cooking water. It also shows water before evaporation allowance, and dry rice and water combined.
How to use the Rice and water ratio
- Replace the example values with your own numbers.
- Review the result and supporting figures as they update automatically.
- Check the formula and assumptions before using the estimate for a decision.
Inputs used
- Dry rice — entered in g
- Water-to-rice ratio — entered in ×
- Extra water for evaporation — entered in g
Rice and water ratio formula
Dry rice × water ratio + evaporation allowance
Assumptions
- The chosen ratio matches the rice type and cooking method.
- Rinsing water is excluded.
Practical guide
Rice and water ratio example and edge cases
How much water is needed for the entered dry rice and ratio? Let's use a concrete example, then look at the assumptions that can move the answer.
Example: A practical rice and water ratio scenario
For this example, use dry rice of 300 g, water-to-rice ratio of 1.5 ×, and extra water for evaporation of 30 g. These are starting values, so replace them with numbers that match your situation.
- Dry rice
- 300 g
- Water-to-rice ratio
- 1.5 ×
- Extra water for evaporation
- 30 g
Calculated result17 ozcooking water
Start with cooking water. Then check water before evaporation allowance, and dry rice and water combined to understand what sits behind the main result.
Example results use the default display profile. The calculator above follows your selected country and units.
How to read the result
- Read the main result first. The supporting figures for water before evaporation allowance, and dry rice and water combined explain how the estimate is built.
- The method is Dry rice × water ratio + evaporation allowance. Keep the units consistent and use values from the same time period.
Edge cases worth checking
When dry rice is unusual
The chosen ratio matches the rice type and cooking method. Double-check this input before relying on the result.
When extra water for evaporation is uncertain
Rinsing water is excluded. Run a lower and higher value to see a useful range.
What changes the result most
Dry rice
Change dry rice on its own first. This shows how strongly it affects the answer.
Water-to-rice ratio
Change water-to-rice ratio on its own first. This shows how strongly it affects the answer.
Extra water for evaporation
Change extra water for evaporation on its own first. This shows how strongly it affects the answer.

Common mistakes
Check dry rice
The chosen ratio matches the rice type and cooking method. Make sure this matches the number you enter.
Keep extra water for evaporation consistent
Rinsing water is excluded. Use the same units and time period throughout the calculation.
Do not rely on one rice and water ratio scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
