Formula notes
Water amount = rice amount x water ratio; presets such as 1:1.5 or 1:2 come from common cooking guidelines for each rice type.
Worked examples
- Example: 2 cups of standard long-grain white rice with a 1:1.5 ratio needs 3 cups of water.
- 1 cup of brown rice with a 1:2 ratio needs 2 cups of water and typically takes longer to cook.
How to use it
- Choose the rice type or set a custom ratio.
- Enter the amount of uncooked rice.
- Read the required water amount and the ratio used.
Frequently asked questions
Why do different rice types need different water?
Absorption and cooking behavior differ by grain type, so each preset ratio reflects common practice for that rice.
Can I use a custom ratio?
Yes. Choose the custom ratio option and enter the ratio you prefer, then input the rice amount.
Limits and interpretation
- Preset ratios are common starting points; actual absorption varies with pot, heat level, and rice freshness.
- The calculator gives the water amount, not cooking time or doneness, so check the rice during cooking.
