}Explanation
The converter converts caster sugar tablespoons into grams. In this converter, 1 tablespoon of caster sugar is about 11.88 grams, 2 tablespoons are about 23.75 grams, and 4 tablespoons are about 47.5 grams.
Caster sugar is finer than granulated sugar and can settle differently, so this converter keeps one explicit tablespoon basis for repeatable recipe scaling.
Caster Sugar uses a reviewed reference of 190 grams per US cup in this dataset. Evidence status: high-confidence. Source basis: King Arthur Ingredient Weight Chart (Baker's Special Sugar / castor sugar: 1 cup = 190g)
Crystal size, packing, moisture, and syrup concentration can change how much mass occupies the same kitchen volume.
