Rice Cooking Ratio Calculator

How much water and how big a pot a batch of rice needs, and how many servings it makes.

The type sets the starting ratio, the typical cook time and a short note. Rice types differ in how much water the grain absorbs.

Cups or grams of dry rice, or the number of cooked half-cup servings you want to end up with.

Cups and grams count dry rice; servings count cooked half-cup portions. Cups and tablespoons are US customary (1 cup = 236.6 ml).

Cups of water per cup of dry rice, by volume. Prefilled from the rice type; change it to match your packet or your last batch.

Water is measured by volume against the rice, the way most packets state it: the ratio is cups of water per cup of dry rice. A cup of dry rice is about 160 to 200 grams depending on the type, so a gram amount is converted to cups with that type's bulk density before the ratio is applied. The cooked volume and the serving count are estimates from typical absorption and expansion, not a promise about your pan, and wild rice and risotto absorb differently because one simmers longer and the other is stirred with liquid added gradually. This is ordinary kitchen arithmetic with conventional starting ratios: it does not judge whether rice is safely cooked or stored, and it runs entirely in your browser with no storage, uploads or network access.
