How to measure walnut halves
How full the cup is and how firmly it is packed changes what it holds, so the same cup can weigh a little more or less in your kitchen. A scale gives the same result every time; the chart below converts any amount.
Source: 128 grams per US cup is the weight per cup in King Arthur Baking’s ingredient weight chart, entry “Walnuts (whole), 1/2 cup = 2 1/4 oz = 64 g”, multiplied by 2 for one cup. A US cup is about 237 milliliters.
