> The pasta converter estimates the cooked weight of dry pasta and how many servings it makes, using a typical cooked-to-dry weight ratio of about 2.25 and a 75–100 g dry portion per person.

## Inputs

- Dry pasta (g, mg, kg, oz, lb)
- Dry portion per person (g, mg, kg, oz, lb)
- Cooked : dry ratio

## Results

- Cooked pasta
- Servings
- Cooking water (≈1 L per 100 g)

## Formula

```
Cooked weight ≈ dry weight × 2.25
```

## Explanation

Dry pasta roughly doubles to two-and-a-half times its weight as it absorbs water.

### How to use the Dry to Cooked Pasta Converter

- **Dry pasta**
- **Dry portion per person**
- **Cooked : dry ratio**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

### What each result means

- **Cooked pasta** = [Dry pasta]×[Cooked : dry ratio]
- **Servings** = [Dry pasta]÷[Dry portion per person]
- **Cooking water (≈1 L per 100 g)** = [Dry pasta]×10

### Example values

## Worked example

Inputs — Dry pasta: 500 g; Dry portion per person: 85 g; Cooked : dry ratio: 2.25.

Results — **Cooked pasta = 1,125 g**; Servings = 5.9; Cooking water (≈1 L per 100 g) = 5 L.

**Does fresh pasta expand?**
Much less; fresh pasta gains only about 20–30%.

**What formula does the Dry to Cooked Pasta Converter use?**
Cooked weight ≈ dry weight × 2.25.
