}Explanation
Use this converter when caster sugar is listed by weight and you want the equivalent in tablespoons. Here, 1 gram of caster sugar works out to about 0.1 tablespoon.
That makes it useful for baking, syrups, and dessert prep when your starting point is grams but your measuring workflow is still spoon-based. The page keeps one caster-sugar factor so the tablespoon estimate stays repeatable.
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.
