Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 120g/cup = cups
  1. Start with 0.4 pounds of walnuts
  2. Convert pounds to grams: 0.4 × 453.59 = 181.44g
  3. 1 cup of walnuts = 120g
  4. 181.44g ÷ 120g/cup = 1.51 cups

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

When a recipe says "1 cup nuts, chopped" vs "1 cup chopped nuts," the first means measure whole then chop. The second means chop first then measure. The weight difference can be significant.

Frequently Asked Questions

About 1.51 cups, based on walnuts having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert pounds to grams (1 pound = 453.592g), then divide by 120 (grams per cup). For 0.4 pounds: 0.4 × 453.592 = 181.44g, then 181.44 ÷ 120 = 1.51 cups.
For the most accurate results, weigh walnuts on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 1.51 cups × 120g/cup = 181.44g, then 181.44g ÷ 453.592 = 0.4 pounds. Or use the Cups to Pounds converter.
