The correct measurement for 1 cup of all-purpose flour is typically:
- 120 grams (weight)
- 8 ounces (weight)
- 1 cup (volume)
However, keep in mind that the way flour is measured can affect accuracy. Sifting flour before measuring can lead to a lighter cup, while scooping flour directly with the measuring cup can pack it in and lead to a denser cup.
For the most accurate results, especially in baking, it’s often recommended to use a kitchen scale to weigh flour.
