Convert Cups to Grams: Chopped Walnuts
Convert cups of chopped walnuts to grams with this complete reference table. 1 cup of chopped walnuts = 120g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because chopped walnuts density can vary by measuring technique.

|---|---|
| 1/8 cup | 15g |
| 1/4 cup | 30g |
| 1/3 cup | 40g |
| 1/2 cup | 60g |
| 2/3 cup | 80g |
| 3/4 cup | 90g |

| 1 1/2 cups | 180g |
| 2 cups | 240g |
| 3 cups | 360g |
| 4 cups | 480g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Chopped walnuts: 1 cup = 120g. Coarsely chopped vs finely chopped can vary by 10-15g/cup. Whole walnut halves: 1 cup = 100g (more air pockets). Toasted walnuts weigh slightly less per cup (moisture lost).
About Chopped Walnuts Density
The density of chopped walnuts determines how much it weighs per unit of volume. At 0.5g/ml, 1 US cup (240ml) of chopped walnuts weighs 120g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
