How we calculate water for rice
Each rice variety has its own water ratio: white 1:1.5; brown 1:2; basmati 1:1.75; jasmine 1:1.5. Water (ml) = rice weight (g) × ratio. Cups = ml ÷ 250. Cooking times: white 18 min, brown 40 min, basmati 15 min, jasmine 18 min.
Example calculation
200 g white rice: water = 200 × 1.5 = 300 ml (1.2 cups), cooking time 18 minutes. 200 g brown rice: water = 400 ml (1.6 cups), 40 minutes. 200 g basmati: water = 350 ml, 15 minutes.
Frequently asked questions
How much water for white rice?
Use a 1:1.5 ratio — 150 ml of water per 100 g of rice. For 200 g that is 300 ml. Some cooks use 1:2 but this can make white rice too soft.
How much water for brown rice?
Brown rice needs a 1:2 ratio — 200 ml per 100 g. The outer bran layer absorbs more water and requires about 40 minutes to cook. Soaking for 30–60 minutes beforehand shortens the time and improves texture.
What is the water ratio for basmati rice?
Basmati uses a 1:1.75 ratio — 175 ml per 100 g. Rinse the grains before cooking and simmer, covered, for about 15 minutes.
Is the ratio the same for jasmine and white rice?
Yes — jasmine (Thai) rice also uses a 1:1.5 ratio and cooks in about 18 minutes. The difference is its characteristic floral aroma.
How do I cook perfect rice step by step?
Rinse until the water runs clear. Add the calculated water. Bring to the boil. Reduce to the lowest heat, cover and cook for the recommended time. Remove from heat and rest for 5 minutes without lifting the lid. Fluff with a fork.
What is the absorption method?
The absorption method means adding exactly the amount of water the rice will absorb — no draining. This preserves more nutrients and starch. Precise measurement is essential, which is what this calculator provides.
How do I convert cups of rice to grams?
One standard 250 ml cup of dry rice weighs about 180–200 g depending on the variety. White rice ≈ 190 g, brown ≈ 185 g, basmati ≈ 180 g. Use a kitchen scale for the most accurate results.
How many portions does 200 g of dry rice give?
200 g of dry rice is a standard 2-person serving as a side dish. After cooking it expands to roughly 500–600 g cooked rice. For 4 people use about 400 g dry.
Why does my rice come out sticky or too hard?
Sticky: too much water, overcooked, or not rinsed (excess surface starch). Hard: too little water or undercooked. Measure precisely and rinse before cooking. Every hob is different — adjust by ±10%.
How do I store cooked rice and can I reheat it?
Store in the fridge in a sealed container for up to 3–4 days. Cool quickly (within 1 hour) before refrigerating. Reheat only once: in a pan with a splash of water or in the microwave covered with a damp paper towel.
The result is indicative. Actual cooking times depend on hob power and rice moisture. Adjust water by ±10% to suit your stove.
