Convert between all-purpose flour and self-rising flour. Calculate exact baking powder and salt amounts for DIY self-rising flour in any quantity.
Your recipe calls for self-rising flour but you only have all-purpose — or vice versa. This is one of the most common baking substitution questions, and getting the ratios wrong can mean flat biscuits or overly-risen muffins. The Self-Rising Flour Calculator converts between the two in seconds.
Self-rising flour is simply all-purpose flour with baking powder and salt already mixed in. The standard ratio is 1 cup flour + 1½ teaspoons baking powder + ¼ teaspoon salt. While this seems simple, scaling it for larger batches requires precision. Too much baking powder creates a bitter, metallic taste. Too little means no rise at all.
This calculator handles conversions in both directions. Need to replace 3 cups of self-rising flour with all-purpose? It tells you exactly how much baking powder and salt to add. Have self-rising flour but a recipe calling for all-purpose with specific leavening? It calculates what (if anything) you need to adjust. Works in cups, grams, and ounces.
Getting flour conversions wrong is a top cause of baking failures. This calculator ensures your leavening ratios are exact, whether you're substituting in a recipe or making a bulk batch. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.

Self-Rising Flour = All-Purpose Flour + Baking Powder + Salt. Per 1 cup (120g) AP flour: add 1.5 tsp (7g) baking powder + 0.25 tsp (1.5g) salt. Per 1 kg AP flour: add 58g baking powder + 12.5g salt.
Result: 3 cups AP flour + 4.5 tsp baking powder + 0.75 tsp salt
3 cups × 1.5 tsp/cup = 4.5 tsp (about 1.5 tbsp) baking powder. 3 cups × 0.25 tsp/cup = 0.75 tsp salt. Whisk together thoroughly before using.
Self-rising flour was invented in the 1840s to simplify baking for home cooks. Before that, bakers had to carefully measure leavening agents for every recipe. The pre-mixed product became especially popular in the American South, where it's the base for countless biscuit, cornbread, and pancake recipes.
Self-rising flour is perfect for quick breads, biscuits, muffins, pancakes, and simple cakes. It should NOT be used for yeast breads (the baking powder interferes), pastry doughs (too much leavening), or recipes that specify "no leavening." All-purpose flour gives you complete control over leavening and is more versatile.
If you bake frequently, make a large batch of self-rising flour: 10 cups AP flour + 5 tablespoons baking powder + 2.5 teaspoons salt. Whisk for 2 full minutes, then sift twice. Store in an airtight container labeled with the date. Use within 4–6 months while the baking powder is still potent.
Yes! Add 1.5 teaspoons baking powder and 0.25 teaspoon salt per cup of all-purpose flour. Whisk very well to distribute evenly.
Yes — "self-rising" (American English) and "self-raising" (British English) are the same product. Use this as a practical reminder before finalizing the result.
Not recommended for yeast breads — the extra leavening interferes with gluten development. It works great for quick breads, biscuits, and pancakes.
Store in an airtight container for up to 6 months. Baking powder loses potency over time, so don't make more than you'll use in a few months.
Some recipes do this intentionally for extra lift. Don't remove either — the recipe was developed with both.
Cake flour has less protein (8% vs 10-12%), so your self-rising version will be softer. It works well for tender biscuits and cakes but not for structured baked goods.
