}Explanation
Use the same 227 g per US cup reference to express butter (unsalted) weight as US cups.
Gram-based recipes and cup-based prep therefore use one explicit assumption. That is especially useful for baking, pie crusts, traditional pastry, and savory doughs where the ingredient may be solid in the jar but measured as a liquid volume. Very small gram amounts are too little to measure reliably in a cup, so cup measuring only becomes practical at larger weights. Butter (Unsalted) is usually easier to weigh directly once melted than to estimate from tiny cup fractions. Solid pieces or semi-solid scoops do not map cleanly to the same cup basis.
