How Much Is 80 Ounces of Walnuts in Cups?
80 ounces of walnuts equals 18.90 cups. Walnuts has a density of 120g per cup. A lighter ingredient like cocoa powder (86g/cup) would fill even more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 80 ounces of walnuts
- Convert ounces to grams: 80 × 28.35 = 2,267.96g
- 1 cup of walnuts = 120g
- 2,267.96g ÷ 120g/cup = 18.90 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Chopped, sliced, and whole walnuts have very different weights per measuring cup. Always match the form specified in your recipe.
