# Rice Water Ratio Calculator

- **Category:** food
- **Description:** Get perfect cooking water amounts for white, brown, jasmine or sushi rice by cups or milliliters.
- **Primary output:** Water for 2 cups of brown rice: 4 cups

## Inputs
- Rice (name: `riceCups`, type: number, example: 2)
- Rice type (name: `type`, type: select)

## Outputs
- Water for 2 cups of brown rice: 4 cups
- Water in milliliters: 948 ml
- Ratio used: 1 : 2

## Formula / methodology
```
Water(cups) = Rice(cups) × Type ratio
Water(ml) = Water(cups) × 237
```

Each rice variety has a conventional absorption ratio: long-grain white 1:1.5, brown 1:2, jasmine 1:1.25 and sushi-style short grain 1:1.1. Multiply your measured rice by the matching factor; milliliters follow at 237 ml per US cup.

## Assumptions & limitations
- Standard US 240 ml measuring cup taken as 237 ml.
- Stovetop absorption method with a tight lid; pasta-method boiling needs far more water.
- Slightly less water compensates for rinsed rice’s surface moisture loss.

## How to use
1. **Measure the dry rice**; Use a proper dry measuring cup and level it off; heaped cups skew the ratio fast.
2. **Match the type**; Select the variety you are actually cooking; jasmine needs noticeably less water than brown.
3. **Add and rest**; Bring to a boil, cover on the lowest heat for the usual time, then rest 10 minutes off-heat before fluffing.

## Example
Two cups of brown rice absorb twice their volume: 4 cups of water, which is 948 ml on a scale or filling line.

Result for these inputs:

```
Water for 2 cups of brown rice: 4 cups
```

## About this calculator
### Why types disagree

Bran layers make brown rice dense and slow-drinking, demanding double its volume; polished sushi rice keeps a surface starch film that turns mushy past 1:1.1. Jasmine sits between; its lower ratio preserves separate, fragrant grains instead of porridge.

### The lid matters more than the number

Absorption math assumes steam stays put. A leaking lid quietly deletes water from your equation, producing crunchy centers no ratio could fix. If results vary pot to pot, suspect the seal before the measurement.

### Rinsing shifts the balance

Rinsing removes loose surface starch; good for texture; and wets the grain. Many cooks shave 5% off the water after rinsing; the note row reminds you where that lever lives.

## FAQs
### Does the rice cooker line match these ratios?

Close; cooker lines assume the included cup (≈180 ml). Use the same cup end to end or measure both by weight instead.

### Why is brown rice 1:2?

The intact bran absorbs more water and cooks slower, so brown needs double volume plus a longer simmer than white.

### Can I halve the recipe?

Yes; ratios scale linearly, though very small batches evaporate proportionally more; add a splash if using under one cup.

### Should I salt the water?

A pinch dissolved into the measured water seasons evenly without disturbing the ratio’s volume.
