Full API documentation

Explanation

Convert fluid ounces of caster sugar to ounces by weight with one ingredient-specific density basis.

Volume ounces become mass ounces without switching to a generic liquid chart. That is especially useful for baking, syrups, and dessert prep where sweetness and structure depend on repeatable weight. The reverse conversion uses the same density reference.

Method & Fluid-Ounce Basis

  • Method basis: fluid-ounce-to-weight conversion anchored to 0.84 oz (weight) per US fluid ounce.
  • Applied formula: ounces (weight) = fluid ounces × 0.84.
  • Consistency rule: snapshot, calculator, FAQ, and table use the same ingredient-specific basis.
