Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 120g/cup = cups
  1. Start with 21.12 ounces of walnuts
  2. Convert ounces to grams: 21.12 × 28.35 = 598.74g
  3. 1 cup of walnuts = 120g

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

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

Frequently Asked Questions

About 4.99 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 ounces to grams (1 ounce = 28.3495g), then divide by 120 (grams per cup). For 21.12 ounces: 21.12 × 28.3495 = 598.74g, then 598.74 ÷ 120 = 4.99 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: 4.99 cups × 120g/cup = 598.74g, then 598.74g ÷ 28.3495 = 21.12 ounces. Or use the Cups to Ounces converter.
