About this calculator
This estimate uses 2.25× the dry weight for cooked pasta, 140 g per approximate cooked cup, and 371 kcal per 100 g of dry enriched pasta. Weight gain and cup volume vary by shape and cooking; check the package for calories. A typical dry portion is about 75–100 g.
Worked example
calculated with the default values below
Dry pasta 100 g Cooked pasta 225 g · Servings (200 g each) 1.13 · Approximate cooked cups 1.61 cups · Estimated calories 371 kcal
Method and assumptions
m_c = 2.25 × m_d Servings = cooked weight ÷ 200 g; approximate cups = cooked weight ÷ 140 g; estimated energy = 3.71 × dry weight in grams (USDA reference for dry enriched pasta, 371 kcal/100 g). Cooking yield and cup mass vary by pasta type and method. This estimate uses 2.25× the dry weight for cooked pasta, 140 g per approximate cooked cup, and 371 kcal per 100 g of dry enriched pasta. Weight gain and cup volume vary by shape and cooking; check the package for calories. A typical dry portion is about 75–100 g. Use the cited guidance and your own measurements, bills or product specifications to choose inputs. Sample defaults are not current local data.

Servings = cooked weight ÷ 200 g; approximate cups = cooked weight ÷ 140 g; estimated energy = 3.71 × dry weight in grams (USDA reference for dry enriched pasta, 371 kcal/100 g). Cooking yield and cup mass vary by pasta type and method.
Frequently asked questions
Why does cooked pasta weigh more than twice the dry weight?
The estimate uses a 2.25× cooked-weight factor: 100 g dry becomes about 225 g cooked. Servings use 200 g cooked each, and cups use 140 g per cup. Calories are estimated from dry weight at 3.71 kcal per gram, based on a USDA reference entry; pasta type and label values vary.
