How many grams are in a cup of flour?
One US cup of flour is about 125 g, or 4.4 oz. To convert other amounts, multiply the number of cups by 125: half a cup is 63 g and a quarter of a cup is 31 g. The converter above does it for any amount and also shows the result in ounces.

About flour
This page uses about 125 g per cup, the figure most recipe charts give for all-purpose flour that has been spooned into the cup and levelled. Sifted flour is lighter, while flour scooped straight from the bag can weigh 140 to 150 g per cup.
Baking tip
Baking is sensitive to flour. Too much makes cakes dry and dense, so when a recipe gives cups and you have a scale, weigh it. Bread flour and wholemeal flour are slightly heavier per cup, and cake flour lighter.
