A general-purpose wheat flour used in most baking recipes, from cookies to bread. It's also commonly labeled "ap flour", "plain flour", "white flour".
All-purpose flour belongs to the Flours group on GramToCup, alongside other ingredients measured the same way in most kitchens. It shows up most often in cookies, cakes, bread. Its density of 125g per US cup is what this calculator uses to convert between grams and cups automatically — no manual lookup required.
All-purpose flour is a dry, milled or ground ingredient full of countless tiny air pockets between the particles. That trapped air is why it weighs relatively little for its volume — the exact weight shifts with how finely it's milled and how much it has settled in the container.
A cup of all-purpose flour is about 1.6× lighter than a cup of granulated sugar (200g/cup), even though both fill the same 1-cup measuring cup.
Common mistake: Scooping the measuring cup directly into the bag, which packs the contents and can add 20g or more per cup.
Spoon all-purpose flour into the measuring cup, then level off the top with a straight edge. Don't scoop directly from the bag — that packs it down and adds extra weight.
When a recipe needs to be exact, weigh it on a kitchen scale instead of using a measuring cup at all — it removes packing and settling from the equation entirely.
Store all-purpose flour in a sealed container — humidity is the main reason the same cup can weigh differently from one day to the next.
100g of all-purpose flour is approximately 0.80 cups, based on a density of 125g per US cup.
1 US cup of all-purpose flour weighs about 125g. Use the calculator above to convert any other amount instantly.
Yes — "ap flour" is another common name for all-purpose flour. The density and conversion values on this page apply either way.
Because cups measure volume and grams measure weight. A cup of all-purpose flour is about 1.6× lighter than a cup of granulated sugar (200g/cup) because the two ingredients have different densities — see the density explanation above for why.
Spoon all-purpose flour into the measuring cup, then level off the top with a straight edge. Don't scoop directly from the bag — that packs it down and adds extra weight.
They're in the same category, but check the density first: Almond flour weighs 96g per cup versus 125g for all-purpose flour. Substituting by weight (grams) keeps a recipe accurate; substituting cup-for-cup can change the result if the densities differ much.
