How Much Is 3.78 Cups of Walnuts in Ounces?
3.78 cups of walnuts equals 16.00 oz. Walnuts has a density of 120g per cup (120g per cup), which means it's relatively light compared to other common cooking ingredients. For comparison, 3.78 cups of honey would be 45.33 oz.
Formula and Step-by-Step
- Start with 3.78 cups of walnuts
- 1 cup of walnuts = 120g
- 3.78 × 120 = 453.6g
- Convert grams to ounces: 453.6 ÷ 28.3495 = 16.00 oz
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.

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
