Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Use the same pasta and cooking/draining method. No universal hydration factor is assumed.
Example Calculation
- Sample dry mass: 100 g
- Sample drained cooked mass: 240 g
- Desired cooked mass: 600 g
A 100 g sample yielding 240 g cooked means 600 g cooked requires 250 g dry at the same yield.
Frequently asked questions
How do I use this calculator?
Enter sample dry mass, sample drained cooked mass, desired cooked mass. The result updates automatically. Use Reset to restore the example values.
What method does it use?
yield factor=sample cooked/sample dry; dry needed=desired cooked/yield.. Use the same pasta and cooking/draining method. No universal hydration factor is assumed.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
