What a cup of water weighs, and why it can differ
USDA’s weight for “1 cup” is 237 g. Next to a cup of water, which holds about 236.6 g, that is 100% of the weight of a cup of water, so it weighs about the same as the same volume of water. The same cup works out at 1 g per millilitre.
USDA lists one cup measure for water (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it.
USDA lists no tablespoon or teaspoon measure for this entry, so that weight is the cup weight divided by the US ratio (16 tablespoons or 48 teaspoons to the cup).
