}Explanation
Convert weight ounces of caster sugar to fluid ounces with the same ingredient density reference used in reverse.
A weighed ingredient can therefore be measured as a pour or small liquid-style volume. That is especially useful for baking, syrups, and dessert prep where sweetness and structure depend on repeatable weight. Caster Sugar can vary with crystal size, moisture, and caking, so the page keeps one explicit basis instead of mixing packing styles.
