Quinoa:
grams to cups.
Uncooked quinoa weighs 170 g per cup — lighter than rice because the small spherical seeds have an irregular surface texture (the outer saponin coating) that prevents tight packing. Like rice, quinoa roughly triples in volume when cooked.

Small spheres, loose packing, lighter cup weight
Quinoa seeds are small and nearly spherical, but their outer surface is slightly rough from the natural saponin coating. This roughness reduces how tightly they can pack in a cup — perfectly smooth spheres would pack more densely (up to about 64% of cup volume), while quinoa achieves closer to 55–60% packing efficiency. The result is 170 g per cup, lighter than similarly sized rice grains. The saponin should be rinsed off before cooking (it tastes bitter and soapy) — this doesn't change the dry weight significantly since saponin is a negligible fraction of the seed mass.
Cooked quinoa: the expansion and protein retention
Quinoa expands to about 3× its dry volume when cooked, similar to white rice. One cup (170 g) of dry quinoa yields approximately 3 cups of cooked quinoa, weighing around 555–570 g (water absorbed and retained). Quinoa is notable for being a complete protein — it contains all essential amino acids, unlike most grains. This protein content doesn't affect density measurements, but it does affect how you season and ratio quinoa in dishes where you're tracking macronutrients. All nutritional calculations should use dry quinoa grams rather than cooked cup measures, since water absorption varies with cooking method.
