Measuring 8 oz 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, 8 Ounces (226.8g) translates to 1.01 US cups (1 cup). By contrast, using the spooned into cup measure (215g/cup — a 10g per-cup shift), 8 oz occupies 1 cup + 2 ¾ tsp (1.05 cups).
Without a kitchen scale, measure 1 cup (16.13 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.
