All-Purpose Flour: Cups to Grams
All-Purpose Flour (also called plain flour, flour) weighs 120 g per US cup — so a recipe in cups and a recipe in grams can be swapped either way. 100 g is 7/8 cup, and 2 cups is 240 g.
💡 Tip: Spoon flour into the cup and level it off — scooping straight from the bag packs in up to 20% extra

Scoop vs. spoon: why your cup can be 20% heavy
Dipping the cup straight into the bag compresses the flour and can pack in 140–150g instead of 120g — up to 20% extra, enough to make bakes dry and dense. For the 120g figure used here, spoon flour loosely into the cup and level the top with a knife, or just weigh it. Weighing is the only way to remove this variation entirely.
