All-purpose flour: Cups to Grams
One US cup of all-purpose flour is about 120 g (flour & dry); a tablespoon is about 7.5 g and 100 g is about 0.833 cups. Convert any amount below. Also called plain flour.
Weight uses all-purpose flour's real density. Volume↔volume and weight↔weight are exact for any ingredient; cup→gram uses a cited reference weight (packing and cup size vary by ±5%).
Note: Spoon-and-level; scooping straight from the bag packs in 20–30 g more.

Why weigh all-purpose flour instead of measuring cups?
A cup measures volume, but recipes really care about how much all-purpose flour you add by weight. One US cup of all-purpose flour is taken as 120 g here, cited from King Arthur Baking, and every conversion on this page routes through that figure. Volume-to-volume and weight-to-weight steps are exact, but the cup→gram crossing depends on how the all-purpose flour is packed, so a kitchen scale is the reliable way to hit the same result every time.
