Measuring 100g of Caster / Superfine Sugar in the Kitchen
Because 1 US Customary Cup (236.6 mL) of caster / superfine sugar weighs 225g when measured poured & leveled, 100 Grams (100g) translates to 0.44 US cups (⅓ cup + 1 tbsp + 2 ¼ tsp). By contrast, using the spooned into cup measure (215g/cup — a 10g per-cup shift), 100g occupies ⅓ cup + 2 tbsp + ¼ tsp (0.47 cups).
Without a kitchen scale, measure ⅓ cup + 1 tbsp + 2 ¼ tsp (7.11 tablespoons total) using poured & leveled technique. Pour and level flat. Because the micro-granules pack closer together than regular granulated sugar, 1 cup weighs a dense 225 grams.
