}Explanation
Use the same 192 g per US cup reference to express rock salt weight as US cups.
Gram-based recipes and cup-based prep therefore use one explicit assumption. That is especially useful for seasoning, brines, curing mixes, and baking recipes where salt type changes the weight behind the same spoon or cup measure. Very small gram amounts are too little to measure reliably in a cup, so cup measuring only becomes practical at larger weights. Rock Salt can vary with crystal size and how tightly it settles, so fine, coarse, and kosher salts should not be treated as interchangeable by volume.

Does this use the same factor as the Cups To Grams page?
Yes. The mirror page uses the same 192 g-per-cup factor, only in the opposite direction.
Does salt type or crystal size change the result for Rock Salt?
Rock Salt keeps one reference basis here, but crystal size and settling can change the real kitchen weight. Fine, coarse, table, and kosher salts should not be treated as interchangeable by volume.
How many cups is 250 g of Rock Salt?
250 g of Rock Salt is 1.30 cups (about 1 1/3 cups) using 192 g per cup.
How do I convert Rock Salt cups back to grams?
Use the mirror Cups To Grams page; multiply cups by 192 to return grams.
