How many grams is 1 tablespoon of dried pasta?

1 tablespoon of dried pasta (dry pasta) weighs

5.9g

That's 0.2oz. An Australian 20ml tablespoon holds 8g.

A level US or UK tablespoon (15ml). USDA doesn't measure a tablespoon of this, so this is a sixteenth of its cup weight.

Pasta shapes pack differently, so a cup of each weighs a different amount. The headline figure is penne.

Where these numbers come from

USDA FoodData Central, SR Legacy, food 20120: “Pasta, dry, enriched”. USDA lists these household measures for it:

1 cup spaghetti = 91g
2 oz = 57g
1 cup elbows = 122g
1 cup penne = 95g
1 cup farfalle = 81g
1 cup rotini = 96g
1 cup shells = 64g
1 cup lasagna = 90g

Fractions of a cup are the cup weight scaled down. The tablespoon figure is the cup weight divided by 16, since USDA doesn't list a tablespoon for this ingredient. The teaspoon is a third of the tablespoon. Metric-cup figures assume a 250ml cup, and Australian tablespoons hold 20ml. Weights under 10g are rounded to 0.1g, everything else to the nearest gram.
