| Standard (1×) | 30g (1.06 oz) | ⅛ cup | 30.9 mL |
| 1.5× Batch | 45g (1.59 oz) | 3 tbsp + ½ tsp | 46.3 mL |
| Double Batch (2×) | 60g (2.12 oz) | ¼ cup | 61.7 mL |

Measuring 30g of Sour Cream in the Kitchen
Because 1 US Customary Cup (236.6 mL) of sour cream weighs 230g when measured spooned & leveled, 30 Grams (30g) translates to 0.13 US cups (⅛ cup). By contrast, using the light sour cream measure (235g/cup — a 5g per-cup shift), 30g occupies ⅛ cup (0.13 cups).
Without a kitchen scale, measure ⅛ cup (2.09 tablespoons total) using spooned & leveled technique. Scoop into a dry measuring cup, pressing lightly with the back of a spoon to eliminate trapped air pockets, and sweep level.
