How to measure ground flaxseed
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: 100 grams per US cup is the weight per cup in King Arthur Baking’s ingredient weight chart, entry “Flax meal, 1/2 cup = 1 3/4 oz = 50 g”, multiplied by 2 for one cup. A US cup is about 237 milliliters.
