"How many grams in a cup of flour?" is one of the most common baking questions — and the answer depends entirely on which flour you're using. All-purpose flour weighs about 125 grams per cup, but bread flour is 130g, cake flour is only 114g, and almond flour is just 96g per cup.
This converter lets you select any type of flour and get precise gram weights for any cup amount. Whether you're converting an American recipe to metric, or want to use a kitchen scale for more accurate baking — just pick your flour, enter the cups, and get the grams instantly.
All values use the spoon-and-level method, which is the standard for accurate volume measuring. If you scoop flour directly from the bag, you'll pack in more flour and your results will be heavier than intended.
How to Use
1. The converter starts with all-purpose flour selected — change it if you need a different type

Frequently Asked Questions
How many grams in 1 cup of all-purpose flour?
One cup of all-purpose (plain) flour weighs 125 grams or 4.4 ounces when measured with the spoon-and-level method. If you scoop from the bag, it can weigh up to 150 grams, which will make your baked goods dry and dense.
How many grams in 2 cups of flour?
Two cups of all-purpose flour weigh 250 grams. For bread flour it's 260 grams, and for cake flour it's 228 grams. Always check which type of flour your recipe calls for — the difference matters.
Why does flour type matter for cups to grams conversion?
Different flours have different protein content and particle sizes, which affects density. Cake flour is finely milled and airy (114 g/cup), while bread flour has more protein and weighs more (130 g/cup). Almond flour is coarser with different-sized particles (96 g/cup). Using the wrong weight can significantly affect your results.
How should I measure flour in cups?
Use the spoon-and-level method: fluff the flour in its container, spoon it into the measuring cup until it overflows, and level with a straight edge. Never tap the cup or pack the flour down. Better yet, use this converter and a kitchen scale — weighing flour gives you perfect results every time.
Is plain flour the same as all-purpose flour?
Yes. 'Plain flour' is the British/Australian term for what Americans call 'all-purpose flour.' Both weigh about 125 grams per cup. In UK recipes, 'self-raising flour' (with leavening added) also weighs about 125g per cup.
How many cups in 500 grams of flour?
500 grams of all-purpose flour equals 4 cups. For bread flour, it's about 3.85 cups. For cake flour, it's about 4.39 cups. This is why weighing is more reliable — '4 cups of flour' means different things depending on the flour type.
