What a cup of table salt weighs, and why it can differ

USDA’s weight for “1 cup” is 292 g. Next to a cup of water, which holds about 236.6 g, that is 123% of the weight of a cup of water, so it is a little heavier than the same volume of water. The same cup works out at 1.2 g per millilitre.

USDA lists one cup measure for table salt (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it.
