Penne

One US cup of penne weighs 95 grams (3.4 ounces). Going the other way, 100 grams is about 1.05 cups.

Also called penne rigate, penne pasta, dry penne, uncooked penne, penne lisce.

Most sites print a number for a cup of penne and do not say where it came from. This page publishes 95 g (3.4 oz) and names all four sources it was checked against: USDA SR Legacy "Pasta, dry, enriched" (FDC 169736), USDA Food Buying Guide for Child Nutrition Programs (penne, enriched, dry), America's Test Kitchen, One-Pot Penne with Chicken and Simple Skillet Sausage Pasta and Prince Penne Rigate and other labels; Barilla measuring chart (barilla.com/en-us/help/measuring-pasta).

Penne, dry, uncooked, poured into the cup and leveled. Based on 0.4015 g/ml, a US cup of 236.5882365 ml. Ounces are weight ounces of 28.35 g.

Where this number comes from

A cup of dry penne weighs 95 g (3.4 oz). USDA, the USDA Food Buying Guide and America's Test Kitchen fall within 7.3% of each other, so this entry publishes USDA's figure.

Penne are short tubes of semolina pasta cut on the diagonal at both ends. In the US they are usually ridged, penne rigate; smooth penne are penne lisce. Ziti and mostaccioli are close relatives: ziti are cut straight across, mostaccioli are the smooth diagonal cut.

USDA SR Legacy "Pasta, dry, enriched" (FDC 169736) lists 1 cup of penne at 95 g. The USDA Food Buying Guide counts about 5 1/8 cups of dry enriched penne to the pound, 88.5 g a cup. America's Test Kitchen gives 8 ounces as 2 1/2 cups in its One-Pot Penne with Chicken and 12 ounces as 3 3/4 cups of penne or another short tube in its Simple Skillet Sausage Pasta, 90.7 g a cup both times. The spread is inside the 10% tolerance for grains and pasta.

Labels scatter much more. Prince prints its penne rigate at "3/4 cup (56g)", 75 g a cup; retailer listings show Ronzoni, Mueller's and Kroger at 2/3 cup (84 g) and De Cecco at 1/2 cup (112 g), all for the same 56 g serving; Barilla's measuring chart gives 2/3 cup per 2 ounces. The labels round the cup to a common fraction at a fixed weight, and for a tube that falls between fractions they disagree by a third, so they are kept as sources without a figure.

The physical check: a tube holds air inside as well as around it. At 95 g a cup is 0.40 g/mL. Dry semolina pasta is about 1.4 g/mL (Biernacka and colleagues, 2018, measured raw spaghetti at 1.34 to 1.45), so only about 29% of a cup of penne is pasta. That is why a cup of penne weighs a fifth less than a cup of elbow macaroni (113 to 130 g), whose short curved pieces pack closer, and about the same as a cup of rotini (84 to 96 g).

Cooked: USDA weighs a cup of cooked penne at 107 g (FDC 169737), the same figure it gives for cooked farfalle and rotini. The Food Buying Guide's yield, 2.60 lb cooked (about 7 3/4 cups) per pound of dry penne, works out to about 152 g a cup, so a cup of cooked penne depends heavily on how firmly it is filled; it is described here rather than published. Barilla counts a 2-ounce serving as 1 1/4 cups cooked.

Practical guidance: use 95 g per cup of dry penne, 48 g per half cup; a 1 lb box holds about 4 3/4 to 5 cups. For a recipe that gives penne in cups, 2 1/2 cups is about 8 ounces. When swapping penne for ziti or rigatoni, weigh rather than measure by the cup.
