Uncooked elbow macaroni weighs 105 grams per cup, and like rice, that figure applies specifically to the dry pasta before cooking — cooked pasta absorbs a substantial amount of water and roughly doubles to two-and-a-half times in volume, so a recipe specifying a cooked-pasta yield represents considerably less dry pasta purchased than the same cup measurement of uncooked elbows would.
Elbow macaroni's curved, tubular shape is functionally significant, not just traditional for mac and cheese — its hollow center and curved shape trap sauce and cheese inside the noodle itself, giving a more evenly coated bite than a solid pasta shape like spaghetti would in the same dish, which is part of why the shape has stayed the default for baked and stovetop mac and cheese specifically.
Dry pasta is a genuinely shelf-stable pantry staple with no meaningful food-safety concern the way cooked pasta or rice has — it keeps for an extended period sealed in a cool, dry pantry, and the main things to watch for are the same general dry-goods signs (pantry pests, a musty smell, or moisture-driven clumping) rather than anything specific to pasta.
Uncooked elbow macaroni's cup weight (100g) roughly doubles once cooked as the pasta absorbs water — like rice, a recipe specifying pasta "cups" without clarifying dry versus cooked can lead to a significantly over- or under-sized batch if the wrong stage is assumed.
Elbow macaroni's curved, hollow shape is specifically well-suited to trapping a cheese sauce inside its curve, which is part of why it's the traditional shape for baked macaroni and cheese rather than a straight noodle that would shed more sauce off its exterior.
Cooking it slightly under the package's suggested time (al dente) is worth doing if it's headed for a baked dish, since it will continue softening in the oven.

Frequently asked questions
How much does elbow macaroni expand when cooked?
It roughly doubles to two-and-a-half-times its dry size once boiled — meaning a recipe written around a measured cup of cooked macaroni is actually calling for a smaller amount of the dry pasta than that same cup measurement of the raw, uncooked shape would suggest.
Why is elbow macaroni specifically used for mac and cheese instead of another pasta shape?
Its curved, hollow shape scoops up and holds onto sauce and cheese inside the tube itself, delivering a more consistently coated bite across the whole dish than a long, solid strand shape manages with the same amount of sauce.
Does whole wheat elbow macaroni weigh the same as regular semolina elbow macaroni?
Close enough for practical conversion purposes — the composition difference between whole wheat and regular durum wheat pasta doesn't meaningfully shift the dry weight per cup, though whole wheat pasta cooks to a slightly different, chewier texture.
How long does dry elbow macaroni last in the pantry?
It's a genuinely shelf-stable dry good, keeping for an extended period (commonly a year or more) sealed in a cool, dry spot — watch for the standard dry-pantry spoilage signs (musty smell, pantry pests, clumping from moisture) rather than a specific pasta concern.
Can dry elbow macaroni be substituted for another small pasta shape by weight?
Yes, reasonably well by weight or dry volume — most small, similarly sized dry pasta shapes (shells, ditalini) are close enough in density to substitute for elbow macaroni in a recipe where the specific shape isn't the point, like a soup.
