About this conversion

Cups to grams for flour is one of the most searched cooking conversions, because US recipes use cups while most of the world (and professional baking) uses grams. The widget above supports all common baking ingredients — change the ingredient to get the correct weight. For plain flour, 1 cup = 125 g. Self-raising flour is the same. Bread flour is slightly denser at 120 g. Wholemeal flour is typically 120–130 g per cup. A key tip: never scoop flour directly from the bag — this compacts it and can add 20–30% extra flour, throwing off your recipe. Spoon flour into the cup measure, level off the top, or ideally use a digital scale. For US baking recipes, multiply cup amounts by the gram value per cup listed in the table above.

Frequently asked questions

How many grams is 1 cup of flour?+
1 cup of plain (all-purpose) flour weighs approximately 125 grams when measured using the spoon-and-level method. Scooping directly from the bag can pack in up to 150–160 g per cup — always weigh for accurate baking.
How many grams is 2 cups of flour?+
2 cups of plain flour equals approximately 250 grams.
How many grams is 1/2 cup of flour?+
1/2 cup of plain flour equals approximately 62.5 grams.
Is a US cup the same as a UK cup?+
No. A US cup is 236.6 ml. The UK does not have a standardised cup measure — UK recipes almost always use grams. Australian and Canadian recipes use a 250 ml metric cup, which holds slightly more flour (about 130 g).
How do I measure flour without scales?+
Spoon the flour into the cup measure and level it off with a straight edge — don't scoop or tap. However, using a kitchen scale in grams is always more accurate for baking.
Does self-raising flour weigh the same as plain flour?+
Yes, self-raising flour is approximately the same density as plain flour: about 125 g per cup. The difference is the added baking powder (which is a very small proportion by weight).
