# How much weight does pasta gain when boiled? [duplicate]

In the diet my dietetician has prescribed me, I have amount of pasta allowed listed for dry (uncooked) pasta.

This is not a problem if I have the foresight to weigh the pasta before boiling, but it is a problem if I buy a dish with ready-made pasta or forget to weigh it before cooking (or just forget how much I had measured, and didn't write down).

Can you give me a rule of thumb / estimate, how much 75g of dry pasta weighs after it's boiled?

• Not an exact duplicate but the answer contains the ratio which I seek, in the calculations to obtain the amount of water absorbed alone (minus pasta): So 100g dry pasta turns into 100g*75/31 = 242g of cooked pasta. My 75g would convert to 187g of cooked pasta. – SF. Feb 2 '16 at 14:13
