Explanation

Use 138 g per US cup as the reference when converting cornmeal from cups to grams.

Recipe scaling stays tied to the US cup standard (236.588 mL) rather than to mixed cup charts. This basis assumes the common spoon-and-level method, where flour is spooned into the cup and leveled rather than packed down.

Method & Cup Basis

Method basis: cup-to-weight conversion anchored to the US customary cup (≈236.6 mL).
Applied formula: grams = cups × 138.
Consistency rule: snapshot, calculator, FAQ, and table use the same ingredient-specific basis.

Methodology

Cornmeal: cups to grams evidence

Direction calculation: Cornmeal — 1 US cup equals 138 grams. Reference: 138 g/US cup. Source basis: King Arthur Ingredient Weight Chart (Cornmeal (whole): 1 cup = 138g)

Particle size, aeration, settling, and whether the cup is scooped or spoon-filled can materially change the mass held by the same volume.
