How many grams is a quarter cup of plain flour?
A quarter cup of plain flour (all-purpose flour) weighs
31g
That's 1.1oz. In a 250ml metric cup it's 33g.
This uses the US cup, the size American recipes mean. A quarter cup is 59ml by volume.
Spoon the flour into the cup and level it off. Scooping straight from the bag packs it down, so you'll get more than this.

Where these numbers come from
USDA FoodData Central, SR Legacy, food 20081: “Wheat flour, white, all-purpose, enriched, bleached”. USDA lists these household measures for it:
- 1 cup = 125g
Fractions of a cup are the cup weight scaled down. The tablespoon figure is the cup weight divided by 16, since USDA doesn't list a tablespoon for this ingredient. The teaspoon is a third of the tablespoon. Metric-cup figures assume a 250ml cup, and Australian tablespoons hold 20ml. Weights under 10g are rounded to 0.1g, everything else to the nearest gram.
