Why Cup Weights Vary in Grains & Rice
Grain cup weight depends on kernel geometry, moisture content, processing style, and interstitial void space. Whole grain white rice consists of dense, polished starch kernels that pack tightly, yielding 185 grams per dry cup. Rolled oats are steamed oat groats flattened by heavy rollers; their large irregular flaked shape creates massive air gaps in a measuring cup, resulting in a light density of just 90 grams per cup. Steel-cut oats bypass rolling and are chopped into dense grain nubs, doubling cup weight to 170-180g. Quinoa seeds are tiny round spheres that settle with minimal void space, weighing 170 grams per dry cup.
