Frequently asked questions

What is Spaghetti Portion Calculator?

Total weight per servings plus the no-scale bundle diameter and an approximate strand count.

When would I actually use this?

Cooking from a recipe that does not match your kitchen: scaling for a different number of people, converting cups to grams, and substituting what you do not have.

What is the most common mistake?

Converting a cup as if it were a volume of weight. A cup of flour and a cup of sugar differ by nearly a third in mass, so a single conversion factor gets one of them badly wrong.

How is Spaghetti Portion Calculator different from Pasta Portion Calculator?

They sit next to each other but answer different questions: Pasta Portion Calculator is the one to open when you need it to work out how much dried pasta and cooking water you need per person. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Rice Portion Calculator is the closest one after this: Work out how much dried rice and cooking water you need per person.

What else is worth having open alongside it?

Air Fryer Converter and Baker's Percentage Calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Volume-to-weight factors are per ingredient, because density is. Cooking times assume a conventional oven at the stated temperature; fan ovens run hotter and need roughly twenty degrees less.
