About this calculator
This is a recipe scaler, not an automatic variety or cooker model. Enter the water-to-dry-rice ratio, measuring-cup volume, cooking time and yield assumption from your package or tested recipe.
Worked example
calculated with the default values below
Rice variety (recipe context only) Long grain · Cups of dry rice 2 · People to feed 4 · Pot diameter 8 in · Recipe water per cup of dry rice 2 · Measuring cup volume (ml) 236.59 · Assumed cooked volume multiplier 3 · Recipe cooking minutes 18 · Recipe resting minutes 10 Water needed 4.00 cups · Rice to water ratio 1 to 2 · Cooked rice 6.00 cups · Cooked rice per person 1.50 cups · Cooking time 18 minutes · Resting time 10 minutes · Estimated water depth in pot 1.15 in · Water 946 ml
Method and assumptions
This is a recipe scaler, not an automatic variety or cooker model. Enter the water-to-dry-rice ratio, measuring-cup volume, cooking time and yield assumption from your package or tested recipe. The variety is context only and does not change those inputs. The initial 2:1 ratio is an example, not a universal recommendation. Cooker fill lines can use different measures; never treat the displayed water depth as a cooker instruction.

Disclaimer
These calculators give general cooking guidance. Ingredient density, oven calibration, altitude and equipment all vary, and safe minimum internal temperatures always take precedence over timings. Follow the food-safety advice issued by your national authority.
Implementation source
This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
water cups = dry rice cups × entered water/rice ratio; water ml = water cups × entered cup ml; cooked yield = dry cups × entered yield factor
The initial 2:1 ratio is an example, not a universal recommendation. Cooker fill lines can use different measures; never treat the displayed water depth as a cooker instruction.
