All-purpose flour: cups to grams
All-purpose (plain) flour is the ingredient where cup measurements go wrong most often: a cup dipped into the bag and packed weighs up to 150 g, a cup spooned in and levelled about 120 g, a difference of 25 % that turns a tender cake into a dense one. Professional recipes are written in grams for exactly this reason.
1 cup all-purpose flour = 120 g · 1 tbsp = 7.5 g · 100 g = 0.83 cups
Based on 120 g per US cup of all-purpose flour, spooned and levelled. Real-world cups vary by about ±10 % for powders.
How to measure all-purpose flour
Fluff the flour with a fork, spoon it into the cup until it overflows, then level with the back of a knife. Never tap the cup or press the flour down. If a recipe says to sift, sift first and then spoon.
Weight is the only measure that does not depend on the container or on how the ingredient was filled. The figure of 120 g per US cup comes from the King Arthur Baking ingredient weight chart; other charts differ by a few percent, which is within the spread between two cooks filling the same cup.
