Full API documentation

Explanation

Convert ounces by weight of all-purpose flour to US cups with the same ounce-per-cup reference used in reverse.

Recipe or label weights can therefore be measured in cups on one consistent basis. That is especially useful for baking and dough work, where small differences in flour volume can change hydration and texture. All-purpose Flour can vary with milling, aeration, and scoop style, so the page keeps one explicit basis instead of mixing spooned, packed, and sifted outcomes.

Method & Cup Basis

  • Method basis: reverse cup conversion anchored to 4.23 oz per 1 US cup.
  • Applied formula: cups = ounces ÷ 4.23.
  • Consistency rule: snapshot, calculator, FAQ, and table use the same ingredient-specific basis.
