Nuts and seeds are measured the same simple way across the board, but their size and shape still change how much fits in a cup. The 7 ingredients here range from Pecans (halves) (109g per cup) to Chia seeds (170g per cup).
Whole nuts and small seeds in this group range from Pecans (halves) at 109g per cup to Chia seeds at 170g per cup, because tiny seeds pack more densely into a cup than larger nut pieces with more air gaps between them.
Every ingredient in this category is measured the same way — scoop and settle, no packing — so density differences here come almost entirely from particle size and shape rather than technique.
How each nuts & seeds ingredient converts at common gram amounts, lightest to heaviest.
| Ingredient | g / cup | 50g | 100g | 200g | 250g | 500g |
|---|---|---|---|---|---|---|
| Pecans (halves) | 109g | 0.46 cups | 0.92 cups | 1.83 cups | 2.29 cups | 4.59 cups |
| Walnuts (halves) | 120g | 0.42 cups | 0.83 cups | 1.67 cups | 2.08 cups | 4.17 cups |
| Cashews (whole) | 137g | 0.36 cups | 0.73 cups | 1.46 cups | 1.82 cups | 3.65 cups |
| Almonds (whole) | 143g | 0.35 cups | 0.70 cups | 1.40 cups | 1.75 cups | 3.50 cups |
| Peanuts (shelled) | 146g | 0.34 cups | 0.68 cups | 1.37 cups | 1.71 cups | 3.42 cups |
| Flax seeds | 150g | 0.33 cups | 0.67 cups | 1.33 cups | 1.67 cups | 3.33 cups |

Whole almonds, eaten as a snack or chopped into baked goods and granola.
Whole cashew nuts, prized for their creamy texture in snacks and sauces.
Shelled peanuts, used whole, chopped, or ground into peanut butter.
Walnut halves with a rich, slightly bitter flavor, common in baking and salads.
Buttery, sweet pecan halves, a classic addition to pies and baked goods.
Tiny nutrient-dense seeds that absorb liquid to form a gel, used in puddings and baking.
Small oil-rich seeds often ground and used as a fiber boost or egg substitute.
Nuts and seeds in this category share one simple rule — scoop and settle, never pack:
Scoop & Settle — Almonds (whole), Cashews (whole), Peanuts (shelled), Walnuts (halves), Pecans (halves), Chia seeds, Flax seeds
Scoop or pour almonds (whole) into the measuring cup and gently shake to settle, then level the top. Don't press down — it settles naturally without packing.
Small seeds like chia and flax settle into a cup with fewer gaps than larger nut pieces like pecan or walnut halves, so they pack denser by volume.
Rounder nuts (cashews, peanuts) fill a cup more efficiently than irregular halves (pecans, walnuts), which also affects their weight per cup.

Use the Gram to Cup Calculator →100g of pecans (halves) is approximately 0.92 cups, based on a density of 109g per US cup.
100g of chia seeds is approximately 0.59 cups, based on a density of 170g per US cup.
The density values here reflect the form listed on each ingredient's page (whole almonds or pecan halves, for example) — chopping a nut smaller lets more pieces fit in the same cup, which increases its weight per cup.
Chia seeds are tiny and fill a cup with very little wasted air space, while walnut halves are large, irregular pieces that leave more gaps — so more chia mass fits into the same volume.
