Grams to cups: bread flour

Working the other way — a recipe in grams, and cups are what you have in the drawer:

Grams of bread flour Cups (approx.)
50 g 0.42 cup
100 g ⅚ cup
125 g 1.04 cups
200 g 1⅔ cups
250 g 2.08 cups
500 g 4⅙ cups

Why the measuring method matters

The 120 g figure assumes bread flour spooned into the cup and leveled. Scooping the cup straight into the bag compacts bread flour and adds weight. That is why recipes written in grams are more repeatable. A scale removes the variable entirely, and it is the reason professional recipes are written in weight.
