}Explanation
Use the same 240 g per US cup reference to express sour cream weight as US cups.
Gram-based recipes and cup-based prep therefore use one explicit assumption. That is especially useful for dips, toppings, baking mixes, and other prep where a scooped or measured volume needs to match a target weight more closely. Very small gram amounts are too little to measure reliably in a cup, so cup measuring only becomes practical at larger weights. Sour Cream can vary slightly with thickness, air pockets, and how compactly it fills the cup, so the page keeps one explicit basis for consistent kitchen reference.
