How Many Cups Is 300 Grams of Flour?
300 grams of all-purpose flour is 2 1/2 cups — 2 and 1/2 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 300 ÷ 120 = 2.50 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 300 grams measure a little less than 2 1/2 cups. For the most reliable results, weigh your flour with a digital scale.
