Important Considerations for Whole Flax Seeds:
Whole flax seeds are relatively dense. A common average is around **10-11 grams per US tablespoon**, or roughly **150 grams per US cup**.
Ground flax seeds (flax meal) will have a different density (typically lighter by volume). This chart is for whole seeds.
When using flax seeds as an egg replacer, they are usually ground first and then mixed with water.
For nutritional calculations or when consistency is key in recipes, measuring by weight with a kitchen scale can be more accurate than volume.
