Flour settles, so a cup's weight depends on how it is filled. This page uses 140 g for a metric cup spooned and levelled. Sifted it can drop to about 125 g; scooped and packed it can reach 160 g. Weigh for the most reliable result.

Related to Plain Flour

Bread Flour

A straight swap with more protein (150 g vs 140 g per cup), so gluten develops further and the crumb turns chewier. Good in pizza, bagels, and rustic loaves; in delicate cakes it can read tough, so reserve it for bakes that want structure. See our Bread Flour converter.

Cake Flour

The tender-crumb swap: cake flour is softer and lower in protein, 7 to 9% against 10 to 12%, giving a finer, lighter result in sponges and cupcakes (130 g vs 140 g per cup). Avoid it for bread and pizza, where the weaker gluten leaves the dough slack. No cake flour on hand? Take 2 tablespoons out of a cup of plain flour and replace them with cornstarch. See our Cake Flour converter.

Brown Sugar

Brown sugar is pressed into its cup while plain flour is spooned in and levelled, which is how one ends up at 220 g and the other at 140 g. Reading a cookie recipe as if both cups were filled the same way is the usual reason the dough turns out wet or sandy. See our Brown Sugar converter.

Self Raising Flour

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 our Self Raising Flour converter.
