Explanation

Use 198 g per US cup as the reference when converting granulated sugar from cups to grams.

Recipe scaling stays tied to the US cup standard (236.588 mL) rather than to mixed cup charts. Granulated Sugar can vary with crystal size, moisture, and caking, so the page keeps one explicit basis instead of mixing packing styles.

Method & Cup Basis

Method basis: cup-to-weight conversion anchored to the US customary cup (≈236.6 mL).
Applied formula: grams = cups × 198.
Consistency rule: snapshot, calculator, FAQ, and table use the same ingredient-specific basis.
