Self Raising Flour Calculator

Cake flour is softer and lower in protein than plain flour (around 7 to 9% vs 10 to 12%), giving a more tender crumb. It is lighter per cup (130 g vs 140 g); for a quick stand-in when out of cake flour, sift 1 cup of plain flour with 2 tablespoons removed and replaced with cornstarch. See cake flour in ounces.

Bread flour carries more protein than plain flour (around 12 to 14% vs 10 to 12%), giving stronger gluten and a chewier crumb in yeasted bakes. It is slightly heavier per cup (150 g vs 140 g); swap by weight in pizza, sandwich loaves, and bagels for a more open, chewy texture. See bread flour in ounces.

Self-raising flour is plain flour with baking powder already blended in, matched in weight per cup (140 g each). Use the self-raising flour calculator to make your own from plain flour, or swap to plain flour and add your own leavener. See self raising flour in ounces.

How do ounces and grams compare as units?

The ratio between them stays fixed regardless of what you are weighing, and the weight converter handles any amount between grams, ounces, pounds, and kilograms for any recipe you follow. Ounces to grams
Why does a cup of flour vary in weight?
Flour compresses easily, so how you fill the cup changes the weight. Spooned lightly and levelled, a metric cup of plain flour is about 140 grams. Sifted first it can fall to around 125 grams, while scooping straight from the bag and packing it down can push it to 160 grams. For consistent baking, weigh flour on a scale rather than measuring by cup.
