How the Rice and Pasta Portion Calculator works
Enter how many people you are cooking for, the food and the portion size.
A standard portion is about 75 g of dry rice or 100 g of dried pasta per person.
Dry rice roughly triples in weight when cooked and pasta more than doubles.
The formula
Worked example
Using the default values shown in the calculator:
| People | 4 |
|---|---|
| Food | Rice |
| Portion size | Standard |
- Rice for 4 at 75 g each = 300 g dry.
- That cooks to about 900 g.
- Use around 450 ml of water, or 1.62 cups of dry rice.
Result:
| Dry weight (g) | 300 |
|---|---|
| Approximate cooked weight (g) | 900 |
| Water to use (ml) | 450 |
| Dry rice in cups (approx.) | 1.62 |
Frequently asked questions
Is the water amount exact?
It is a guide. Absorption-method rice uses about 1.5 times its weight in water, though it varies by variety. Pasta is boiled in plenty of water, about 1 litre per 100 g.
Does it apply to other grains?
Roughly. Quinoa and couscous cook up to about 3 times their dry weight.
