Self-rising flour substitute and how much leavening it carries
Self-rising flour is just plain flour with leavening built in — roughly 1½ teaspoons of baking powder and ¼ teaspoon of salt per cup. That is why you cannot swap it one-for-one with all-purpose flour without changing the rest of the recipe.
Out of it? Whisk those amounts into a cup of all-purpose flour and use it straight away. Because the baking powder weakens with time, mix only what you need rather than storing a big batch.

There are 16 tablespoons in a cup, so one tablespoon of self-rising flour weighs roughly 7.81 g — and a teaspoon 2.6 g.
Is self-rising flour heavy or light for its category?
A cup of self-rising flour weighs 125 g, which puts it 11th by weight among the 15 flours & starches on this site. Its nearest neighbours are cassava flour at 120 g and bread flour at 127 g per cup.
Swapping these by the cupful is not like-for-like. A cup of bread flour in place of self-rising flour puts roughly 2 g more in the bowl, so match the grams rather than the cups.
Common questions about measuring self-rising flour
- How many grams is 1 cup of self-rising flour?
- A level US cup of self-rising flour comes to roughly 125 g (4.41 oz on a scale).
- How many grams is 2 cups of self-rising flour?

- How do I make self-rising flour?
- For each cup, whisk together 1 cup of all-purpose flour, 1½ teaspoons of baking powder, and ¼ teaspoon of salt. Make it fresh, since the baking powder loses strength over time.
- Is self-rising flour the same as self-raising flour?
- Yes. 'Self-rising' (US) and 'self-raising' (UK) are the same product: plain flour with baking powder and a little salt already mixed in. Both weigh about 125g per cup.
- Can I use self-rising flour instead of all-purpose flour?
- Only if you also remove the recipe's baking powder and salt — otherwise it will over-rise and taste salty. It works best in recipes actually written for self-rising flour, like quick biscuits and some pancakes.
- How many cups is 100g of self-rising flour?
- 100 g of self-rising flour works out at roughly 3/4 cup.
- Why do my numbers differ slightly?
- Flour compresses. Dipping the cup into the bag can pack in 20% more than spooning it in loosely and levelling the top, and sifting first makes it lighter still. A scale removes the guesswork.
