Frequently Asked Questions

About 8.47 oz, based on walnuts having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 120 (grams per cup for walnuts), then divide by 28.3495 to convert grams to ounces. For 2 cups: 2 × 120 = 240g, then 240 ÷ 28.3495 = 8.47 oz.
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: 8.47 oz × 28.3495 = 240g, then 240g ÷ 120 = 2 cups. Or use the Ounces to Cups converter.
