Measuring 8 oz 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, 8 Ounces (226.8g) translates to 1.00 US cups (1 cup). By contrast, using the melted butter (liquid) measure (227g/cup — an identical per-cup density), 8 oz occupies 1 cup (1.00 cups).

In US stick markings, 8 oz corresponds to 2 butter sticks (15.99 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.
