Measuring 120g of Unsalted Butter in the Kitchen

Because 1 US Customary Cup (236.6 mL) of unsalted butter weighs 227g when measured packed into cup / 2 sticks, 120 Grams (120g) translates to 0.53 US cups (½ cup + 1 ¼ tsp). By contrast, using the melted butter (liquid) measure (227g/cup — an identical per-cup density), 120g occupies ½ cup + 1 ¼ tsp (0.53 cups).

In US stick markings, 120g corresponds to 1.06 butter sticks (8.46 tablespoons). In the US, 1 standard stick equals 1/2 cup (8 tablespoons or 113.5g); two sticks equal exactly 1 cup (227g). When packing softened butter from a block, press out air gaps.
