All-Purpose Flour: cups to grams
Flour is the ingredient where cup measurements go wrong most often, because it compresses. Scooping straight from the bag can pack in up to 20% more than spooning it in loosely.

Cup standards compared
Convert cooking volumes
The charts above cover weight. If you also need to move between cups, decilitres, millilitres and spoons, this converts any volume:
1 cup (US) in every unit
A US cup is 236.6 ml, a metric cup is 250 ml and a UK tablespoon is larger than a US one — so the system your recipe was written in matters. Pick the matching unit rather than assuming.
Questions
How many grams is 1 cup of all-purpose flour?
One US cup of all-purpose flour weighs 120 grams. That works out to a density of about 0.51 g per mL.
How many cups is 100 g of all-purpose flour?
100 g of all-purpose flour is about 0.83 cups, or roughly 13.3 tablespoons.
Why can’t I convert cups to grams directly?
A cup measures volume and a gram measures weight, so the conversion depends entirely on the ingredient. A cup of all-purpose flour is 120 g, but a cup of honey is 340 g and a cup of cocoa powder is only 84 g.
Does the cup size matter?
Yes. A US customary cup is 236.59 mL, a US legal cup is 240 mL and a metric cup is 250 mL. Using a metric cup for all-purpose flour gives 127 g instead of 120 g — about 6 percent more.
