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 an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
What is a Cup?
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
1 ounce of walnuts is 0.24 cups. The conversion depends on the density of walnuts and scales proportionally for any amount.
If you have a kitchen scale, weighing walnuts gives you an exact starting point for this conversion. If you need to measure by volume instead, spoon the ingredient into the measuring cup and level it off with a straight edge.
Close, but not exactly. The ounces to cups conversion for walnuts may vary slightly between brands depending on moisture content and how the ingredient is measured.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of walnuts fills a different number of cups than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
