About
Shelled pistachio seeds pack loosely into measuring cups, weighing about 5.0 ounces (142 grams) per cup.
Pistachio kernels have a bulk density of about 37 pounds per cubic foot (0.6 grams per milliliter). Because their irregular, curved shapes leave open spaces between the seeds, they take up considerably more room than powders or liquids of the same weight. A standard 1-quart container holds around 1.3 pounds (568 grams) of loose kernels, which is typical for medium-sized shelled tree nuts.
From Wikipedia
The pistachio is a small to medium-sized tree of the cashew family. The tree produces seeds that are widely consumed as food.
