About
Coriander seeds are the light, hollow dried fruits of the cilantro plant, weighing only 3.2 ounces (90 grams) per cup.
Whole coriander seeds have a low bulk density of around 24 pounds per cubic foot (0.38 grams per milliliter). Because the small round husks are mostly hollow, they leave large pockets of empty air when poured into a container. A cup of these seeds weighs roughly one-third as much as an equal volume of water. They take up far more space for their weight than denser spices like whole black peppercorns.
From Wikipedia
