100 g: 0.8cups; of a US cup

Self-rising flour already has baking powder and salt mixed in, so a recipe that uses it leaves those out. Its cup weighs the same as plain flour, which is why it is easy to mistake one for the other on the shelf. Mixing your own from plain flour, baking powder and salt is possible, but the amounts vary between recipes, so follow the one you are cooking from rather than a rule of thumb. It is common in biscuits, pancakes and quick breads, and in some countries it is the standard flour on the shelf, so a recipe from abroad may assume it without saying.

What a cup of self-rising flour weighs, and why it can differ

USDA’s weight for “1 cup” is 125 g. Next to a cup of water, which holds about 236.6 g, that is 53% of the weight of a cup of water, so a lot of the cup is air. The same cup works out at 0.53 g per millilitre.

USDA lists one cup measure for self-rising flour (“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).
