The maths behind it

This tool uses Water = dry rice × the ratio for that variety. Rice roughly triples in weight when cooked, so one cup of dry rice serves about three people. Every intermediate value is shown on screen, so the result can be checked by hand.

Rinse white and basmati until the water runs clear — that removes surface starch and is the difference between separate grains and a sticky mass. Do not rinse risotto or paella rice, where that starch is the point. Leave the lid on: every peek releases the steam doing the cooking.

Frequently asked questions

Does the Rice Water Calculator cost anything?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Is the Rice Water Calculator safe to use with private information?
No. The Rice Water Calculator runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
Can I check the maths myself?
It uses Water = dry rice × the ratio for that variety. Rice roughly triples in weight when cooked, so one cup of dry rice serves about three people. The full working is printed under the result, so you can follow every step rather than trusting a black box.
What is the Rice Water Calculator used for?
In practice it gets used for three things: getting the water right for a rice type you rarely cook. Scaling for the number of people. Knowing the simmer time for brown or wild rice. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there anything to watch out for?
Rinse white and basmati until the water runs clear — that removes surface starch and is the difference between separate grains and a sticky mass. Do not rinse risotto or paella rice, where that starch is the point. Leave the lid on: every peek releases the steam doing the cooking.
Which values should I know?
White / basmati is 1 : 1.5. Jasmine is 1 : 1.25. Brown is 1 : 2.25, 40 min. These are printed on the page itself, so you do not have to take them on trust.
How precise is the result?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
