Use our dry to cooked pasta calculator to get estimated amount of cooked pasta you’ll end up with from a given quantity of dry pasta (long, short, or soup) using CP = DP × R formula.
If you start with 100g of dry spaghetti, the calculator might tell you to expect about 200-250g of cooked pasta.

Dry to Cooked Pasta Conversion Formula
The formula for converting dry pasta to cooked is:
Cooked pasta weight = Dry pasta weight × Expansion factorThe expansion factor varies depending on the pasta shape but typically ranges from 1.5 to 2.5.
For long pasta like spaghetti, using an expansion factor of 2:
- 100g dry pasta × 2 = 200g cooked pasta
Let’s say you have 200 grams of dry penne pasta and the ratio of dry to cooked penne is 1:2. To calculate the weight of cooked pasta, plug in the values:
CP = 200 grams × 2 = 400 grams
A 200 grams of dry penne pasta will yield approximately 400 grams of cooked pasta.
How Do You Convert Dry Pasta to Cooked?
- Measure the weight of dry pasta you want to cook.
- Choose the appropriate ratio for the type of pasta you’re using. As a general rule:
- Long pasta (e.g., spaghetti): 1:1.5 to 1:2
- Short pasta (e.g., penne): 1:1.5 to 1:2
- Soup pasta (e.g., ditalini): 1:1.5 to 1:2
- Plug the values into the formula: CP = DP × R
- Calculate the weight of cooked pasta and use it in your recipe.
Converting 80g of dry penne
Dry weight: 80g
Shape: Short pasta
Expansion factor: ~2.1
80g × 2.1 = 168g cooked penne (approximately)
Assume you want to cook 8 ounces of dry spaghetti. Using a ratio of 1:2, we can calculate the amount of cooked spaghetti:
CP = 8 ounces × 2 = 16 ounces
8 ounces of dry spaghetti will yield approximately 16 ounces of cooked spaghetti.
1 Cup of Dry Macaroni Equals How Much Cooked?
One cup of dry macaroni typically yields about 2 to 2.5 cups of cooked macaroni.
1 cup dry macaroni ≈ 100g
Expansion factor for macaroni ≈ 2.2
Cooked weight: 100g × 2.2 = 220g
220g cooked macaroni ≈ 2.25 cups
100g Uncooked Pasta to Cooked
- Long pasta (spaghetti, linguine): 100g dry → 200-220g cooked
- Short pasta (penne, fusilli): 100g dry → 210-250g cooked
- Filled pasta (ravioli, tortellini): 100g dry → 170-200g cooked
100g dry fusilli
- 100g × 2.3 (expansion factor) = 230g cooked fusilli
How Much Does 2 oz Dry Pasta Weigh Cooked?
Two ounces (56g) of dry pasta typically yields about 4-5 ounces (113-142g) when cooked.
2 oz (56g) dry spaghetti
56g × 2.1 (expansion factor) = 117.6g cooked spaghetti
