1/2 cups of all-purpose flour in grams
1/2 cups of all-purpose flour ≈ 62.5 grams
That is about 2.2 ounces. Also sold as plain flour. One US cup of all-purpose flour weighs 125 g.
Why this number is approximate
The single most variable ingredient in any recipe. Scooping straight from the bag compacts the flour and can yield 150 g or more; spooning it into the cup and levelling gives about 125 g. A 20% error in flour is the difference between a tender crumb and a brick — this is the ingredient most worth weighing.

Weigh it if you can
Volume measures are convenient but imprecise — the same cup can hold noticeably different amounts depending on how the ingredient is packed, how humid the room is, and whether it was sifted. A digital kitchen scale removes the variable entirely, which is why professional and European recipes give weights. If you bake regularly, a scale is the cheapest accuracy upgrade available.
Frequently asked questions
How many grams is 1/2 cups of all-purpose flour?
About 62.5 grams, or 2.2 ounces.
How many grams in a cup of all-purpose flour?
Roughly 125 grams per US cup.
Is a US cup the same as a metric cup?
No. A US customary cup is 236.6 ml; a metric cup — used in Australia, New Zealand and much of Europe — is 250 ml, about 6% larger. An imperial cup, still seen in older British recipes, is 284 ml. For a cup of all-purpose flour that is a difference of roughly 7.09 g between US and metric.
Should I sift before or after measuring?
It matters, and recipes are often ambiguous. "1 cup sifted flour" means sift first, then measure — which gives less flour than "1 cup flour, sifted", where you measure first. When in doubt, weigh.
