Why does walnuts (halves) weigh what it weighs?
Whole nuts trap a lot of air between pieces, so cup measurements vary wildly depending on the size and orientation of each nut. Chopped or sliced nuts pack more tightly and weigh more per cup. For consistent results in baking, weigh nuts before adding them — especially when they are a structural component like in nut flours or pralines.
For walnuts (halves) specifically, 1 cup weighs 120g. 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.
Recipes that originated outside the United States almost always specify weight in grams. Translating these to US cup measurements introduces error in every step. The ChefVault app handles the math automatically — paste a recipe, hit convert, get a clean weight-based version.
