The number of cups required for 180 grammes of flour depends on the flour’s density. If the density of all-purpose flour is 125 grammes per cup, then 180 grammes is equivalent to 1.44 cups.
Likewise, the density of plain flour is 125 grammes per U.S. cup, therefore 1.44 cups of plain flour equals 180 grammes. In contrast, the density of cake flour is 100 grammes per cup; consequently, 180 grammes of cake flour is comparable to 1.80 cups. Bread flour has a density of 127 grammes per cup; hence, 180 grammes of bread flour is about comparable to 1.42 cups.
