1 Cup Flour in Grams

1 cup of flour weighs:

125g

US cup (240 ml)

130g

Metric / AU cup (250 ml)

American recipes mean the 240 ml cup; Australian, British and New Zealand recipes mean the 250 ml metric cup. If the recipe does not say, the cuisine usually tells you — see the full cups to grams guide.

Flour is the ingredient where cup measures go wrong most often. Scooped straight from the bag, a cup of plain flour can weigh 145 g or more; spooned in loosely and levelled, it lands around 125 g. That 20 g spread is the difference between a tender cake and a dry one, which is why almost every serious baking recipe now gives weights.

Questions

Frequently asked questions

How many grams is 1 cup of flour?
1 US cup of flour is 125 g. In an Australian, UK or NZ metric cup (250 ml) it is 130 g. Weighing is more accurate than measuring by volume.
How many grams is half a cup of flour?
Half a US cup of flour is 63 g, and three-quarters of a cup is 94 g.
Why does my cup of flour weigh more than 125 g?
Because of how you filled it. Dipping the cup into the bag compacts the flour and can add 15–25 g. The standard figure assumes the spoon-and-level method: stir the flour, spoon it lightly into the cup, then sweep the excess off with a straight edge.
Is bread flour the same weight as plain flour?
Very nearly — bread flour is about 127 g per cup against 125 g for plain, a difference too small to matter in practice. Cake flour is lighter at about 114 g, and wholemeal sits around 120 g.
Should I weigh flour instead of measuring cups?
For baking, yes. A scale removes the single largest source of variation in home baking and is faster than levelling a cup. For thickening a sauce or dusting a surface, cups are perfectly fine.
