About This Calculator
The Dry to Cooked Pasta Converter helps home cooks, meal planners, and professional chefs quickly convert between dry and cooked pasta quantities. Whether you are scaling a recipe for a dinner party, meal prepping for the week, or simply wondering how much pasta to cook, this tool provides instant and accurate conversions using the standard 1:2 expansion ratio.
Pasta approximately doubles in weight and volume when cooked because it absorbs water and the starches gelatinize during the boiling process. The calculator applies this simple formula: cooked pasta = dry pasta × 2. For the reverse conversion, it divides the cooked amount by 2. The tool supports grams for precise weight measurements, cups for volume-based recipes, and ounces for US customary measurements, making it useful across cooking traditions worldwide.

Frequently Asked Questions
How does the dry to cooked pasta calculator work?
The calculator uses the standard 1:2 expansion ratio. Simply enter the amount of dry pasta and it multiplies by 2 to give the cooked pasta equivalent. You can also reverse the calculation to find dry pasta from cooked pasta. The tool supports grams, cups, and ounces.
What is the ratio of dry to cooked pasta?
The standard ratio of dry to cooked pasta is approximately 1:2. This means 100 grams of dry pasta yields about 200 grams of cooked pasta. Similarly, 1 cup of dry pasta yields about 2 cups of cooked pasta. The ratio can vary slightly from 1:1.5 to 1:2 depending on pasta shape and cooking time.
How much dry pasta do I need per person?
A typical serving of dry pasta is about 70-100 grams (2.5-3.5 ounces) per person as a main dish, or 50-70 grams (1.75-2.5 ounces) as a side dish. This yields approximately 140-200 grams of cooked pasta per person for a main course, or 100-140 grams for a side.
Does the expansion ratio vary by pasta shape?
The 1:2 ratio works well for most common pasta shapes. Short pasta like penne, fusilli, and elbows expands to roughly double its original volume. Long pasta like spaghetti and fettuccine also roughly doubles in weight when cooked. The ratio may vary slightly based on cooking time and pasta brand, but 1:2 is a reliable standard estimate.
Can I convert cooked pasta back to dry?
Yes, select the Cooked to Dry mode in the calculator. Enter the amount of cooked pasta and it divides by 2 to determine the original dry pasta quantity. This is useful when you have leftover cooked pasta and need to know how much dry pasta was used, or when adapting recipes that specify cooked pasta amounts.
How many cups of cooked pasta from 1 cup of dry?
One cup of dry pasta yields approximately 2 cups of cooked pasta. This 1:2 ratio is the standard for most pasta shapes. For short pasta like macaroni or penne, 1 cup dry gives about 1.9 to 2 cups cooked. For long pasta like spaghetti, the volume measurement is less precise, so weighing is recommended.
How much does 100g of dry pasta weigh when cooked?
100 grams of dry pasta weighs approximately 200 grams when cooked. During cooking, pasta absorbs water and expands to about double its original weight. The exact amount depends on cooking time and pasta type, with al dente pasta absorbing slightly less water than fully cooked pasta.
