Flour Grams to Cups Converter
Convert all-purpose flour, bread flour, cake flour, almond flour, and specialty starches between grams and cups. Master density variations caused by milling fineness and protein content.
Direct Answer
Not all flour weighs the same. A cup of all-purpose flour is 125g, bread flour is 130g, and almond flour is 112g. Pick your exact type below.
Because different ingredients within the flour category have varying particle sizes and moisture levels, measuring by weight in grams ensures perfect baking results.

Density Dynamics in Flour
Flour density varies dramatically based on grain protein content, milling fineness, and compaction state. Hard wheat varieties milled into bread flour contain higher protein levels (12-14%), yielding denser starch granules that weigh approximately 130 grams per cup. Soft wheat cake flours are milled extra-fine with lower protein (7-9%), settling into lighter bulk volumes around 114 grams per cup. Non-grain options like nut flours contain high oil content and no gluten matrix, causing ground almond flour to compact tightly to 112-115g per cup depending on whether it is blanched or skin-on. Furthermore, sifting flours incorporates air pockets that reduce cup mass by 10-15%, whereas dipping a measuring cup directly into a bag compresses particles and adds up to 20g of unintended weight.
Flour Substitution Rules: Weight vs Volume
When substituting flours in baking, always swap by weight in grams rather than volume cups. A 1:1 volume swap of almond flour (112g/cup) for all-purpose flour (125g/cup) results in a 10% starch deficiency and excess fat. For bread flour, swapping 100g of all-purpose flour for 100g of bread flour maintains correct total mass, though hydration levels may require a 2-3% liquid adjustment due to higher protein absorption rates.

How many grams is 1 cup of all-purpose flour?
One US customary cup of all-purpose flour weighs exactly 125 grams when spooned into the cup and leveled off with a straight edge.
Why does bread flour weigh more than cake flour?
Bread flour is ground from hard spring wheat with 12 to 14 percent protein content, making its particles denser (130g/cup) than soft wheat cake flour (114g/cup).
Can I substitute almond flour for white flour by weight?
Swapping by weight in grams ensures correct mass, but nut flours lack gluten and contain high natural fats, requiring additional binding agents like eggs or tapioca starch.
Does sifting flour change its weight in grams?
Sifting alters volume by trapping air, reducing a cup weight from 125g down to ~110g. However, 100 grams of flour remains 100 grams regardless of sifting.
What is the correct way to measure flour without a scale?
Fluff the flour with a fork, spoon it gently into your measuring cup without packing, and level off the top with the flat back of a butter knife.
