Why does sunflower seeds (shelled) weigh what it weighs?

Tiny seeds pack tightly and weigh more per cup than you might expect. Seeds also absorb moisture differently — chia and flax can absorb several times their weight in liquid, which matters for hydration-sensitive recipes. Weighing seeds gives you predictable results, especially in bread baking and gluten-free formulas.

For sunflower seeds (shelled) specifically, 1 cup weighs 140g. That is the figure to plug into recipes calling for cup measurements when you want gram precision. ChefVault stores this density (and 118 others) so you never have to look it up twice.
