Rice to Water Ratio Calculator

This calculator uses established water-to-rice ratios for each rice type: basmati 1:1.5, long grain 1:1.75, brown 1:2.5, sushi 1:1.2, jasmine 1:1.5, and wild 1:3. These are traditional cup-to-cup volume ratios applied here as grams to millilitres. Uncooked rice is a little lighter than water (about 0.83 g/ml), so this convention gives firm, well-cooked grains — add a splash of Extra Water in Advanced Options if you like your rice softer.

Serving size defaults to 75g of dry rice per person (adjustable in Advanced Options — allow 60-75g for a side and 75-100g for a main), which produces roughly 180g of cooked white basmati. Cooked weight is bounded by conservation of mass (rice plus water added), so at these firmer ratios white rice grows to about 2.4 times its dry weight rather than the wetter-method "triple". Cooking times are for the absorption method (lid on, simmer until water is absorbed), which gives the best results for all rice types.
