How Many Cups Is 400 Grams of Flour?
400 grams of all-purpose flour is 3 1/3 cups — about 3 and 1/3 cups. Flour is measured at about 120 grams per cup when you spoon it into the cup and level it off, so the math is simply 400 ÷ 120 = 3.33 cups.
Because flour compacts easily, scooping straight from the bag (dip-and-sweep) can pack in up to 140 grams per cup, which would make 400 grams measure a little less than 3 1/3 cups. For the most reliable results, weigh your flour with a digital scale.
