Flour in Grams: How Many Grams in a Cup of Flour?

1 cup of all-purpose flour weighs 125 grams. Scooping flour directly from the bag compresses it and can add 30–50g extra per cup. Always spoon flour lightly into the measuring cup and level off the top with a straight edge — this is the most common source of error in baking.

For the most accurate results, weigh your flour with a digital kitchen scale — the values below assume a level, unpacked cup.

Who is this useful for?

If you're an international cook following US-based recipes, you'll often encounter cup measurements for flour. However, many countries — including those in Europe and Asia — primarily use grams for precision. Converting flour to grams ensures consistent and reliable results, whether you're baking or cooking.

Why accuracy matters for flour

Precision is especially important when using flour in baking and cooking. Even small variations in weight can impact the texture, consistency, and flavour of your dish. For example, too much flour in a recipe can make baked goods dense, while too little may cause them to be too dry or crumbly.
