How to measure it

Chopped walnuts weigh about 117 g a cup. Like almonds, the number is all about the gaps: walnut halves bridge over big air pockets at about 100 g a cup, while finely chopped pieces settle to nearly 130 g.

Pecans track walnuts almost exactly, chopped at about 110 g a cup, so this page works for both. If a recipe says a cup of nuts without naming a form, chopped is the safest assumption for cookies and quick breads.

Density source: Government food composition data (chopped walnuts). Method assumed: Chopped pieces. Halves are lighter, ground meal heavier.
