Rice Cooker Calculator
How much rice and water do you need, for how many people? Enter servings and rice type to get uncooked rice, water and cooked yield — with the right water ratio per type.
Rice for 4 servings — white rice (long-grain)
180 g uncooked rice — 7/8 (0.97 cups) · 345 ml water
| What you need | Amount |
|---|---|
| Uncooked rice | 180 g — 7/8 (0.97 cups) |
| Water (ratio 1:1.5) | 1 1/2 (1.46 cups) — 345 ml |
| Cooked yield (approx.) | 3 (3 cups) — about 540 g |
Rinse until the water runs clear — it removes surface starch and stops the rice going gummy.
Do not lift the lid while it steams, and let the rice rest 10 minutes after cooking before fluffing. One serving is about 1/4 cup (45 g) of uncooked rice, which cooks to about 3/4 cup.
Formula used: Uncooked rice = servings × 45 g (1/4 cup each). Water = uncooked rice × 1.5 (1:1.5 for white rice (long-grain)). Cooked yield ≈ 3× the uncooked weight, about 3/4 cup per serving.
How the rice cooker calculator works
Enter the number of servings and the rice type. One serving is about 1/4 cup (45 g) of uncooked rice, which cooks to about 3/4 cup. The water ratio depends on the type: white rice 1:1.5, basmati 1:1.5, jasmine 1:1.25, brown rice 1:2. The tool gives uncooked rice, water and cooked yield.
Watch out for
Rinse white rice until the water runs clear — it removes surface starch and stops the rice going gummy. Do not lift the lid while it steams, and let it rest 10 minutes after cooking before fluffing. Brown rice needs more water and more time, and it does not suit the same ratio as white rice.
