How to measure sunflower seeds
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: 140 grams per US cup is the weight per cup in King Arthur Baking’s ingredient weight chart, entry “Sunflower seeds, 1/4 cup = 1 1/4 oz = 35 g”, multiplied by 4 for one cup. A US cup is about 237 milliliters.
