4 Cups of Flour in Grams

Four cups of all purpose flour is 480 grams

Four cups is the batch size behind a pair of sandwich loaves, a 9 by 13 sheet cake and most double recipes, so the gram figure is worth pinning down before anything gets sifted. On the King Arthur Baking ingredient weight chart one cup of all purpose flour is 120 g, and 4 x 120 = 480 g.

The package label agrees. Gold Medal all purpose flour prints a serving as 1/4 cup and 30 g, so sixteen quarter cups make 16 x 30 = 480 g, and those sixteen servings carry 16 x 110 = 1,760 calories.

USDA FoodData Central record 168936 takes a different view of the same cup: 125 g, which puts four cups at 4 x 125 = 500 g. The 20 g gap is 500 / 480 = 1.042, a 4.2 percent spread, and it comes from the fill the database assumes rather than from the wheat. Both columns appear in the table below so you can match whichever number your recipe was built on.

Set the scale to ounces and 480 g reads 480 / 28.3495 = 16.93 oz, or 1.06 lb. In spoons, four cups is 4 x 16 = 64 level tablespoons, and each tablespoon holds 480 / 64 = 7.5 g at the chart weight.

Spooned, scooped or packed: four cups swings 160 grams

The 120 g figure is not a property of flour. It is a property of one fill technique: loosen the flour, sprinkle it into the cup, then sweep a straight edge across the top. America's Test Kitchen fills cups by dip and sweep instead, and its standard is 5 oz, or 142 g per cup, an average taken from dozens of volunteers who each measured a cup their own way. The same test kitchen notes that the fill alone can move a cup by 20 percent. King Arthur puts the ceiling at 160 g for flour that has been pressed down in the bag.

Run the middle row by hand: 4 x 142 = 568 g, which is 88 g more flour than the chart calls for, and 88 / 480 = 18 percent. The packed row is worse at 4 x 160 = 640 g, or 640 / 480 = 1.333, a third more flour than the recipe expects. Drop 568 g of flour into a dough written for 312 g of water and the hydration falls to 312 / 568 = 54.9 percent, closer to a bagel than a sandwich loaf.

Weigh your own cup three times the way you normally fill it and average the result. If it lands at 140 g, every four cup recipe carries 4 x 20 = 80 g of extra flour, and the fix is either a lighter hand or, better, 480 g straight into the bowl.

Four cups of twelve flours, from 368 g to 652 g

Flour is a family, and each member packs differently. The King Arthur chart prints a separate weight per cup for every type, and at four cups the spread runs from 368 g to 652 g, a range wider than the gap between the two cup standards above.

The two ends behave differently in a bowl. Four cups of whole wheat is 4 x 113 = 452 g, so a cup for cup swap from all purpose removes 28 g of flour while the water stays put, and the bran also drinks more, which is why whole grain formulas hold the flour weight and add liquid. A gluten free blend goes the other way: 4 x 156 = 624 g, and 624 / 480 = 1.30, thirty percent more flour than the recipe writer had in mind. Semolina is the heaviest cup on the chart at 4 x 163 = 652 g because the coarse durum granules settle into less air.

Two entries surprise people. Bread flour and all purpose share the same 120 g cup, and King Arthur lists unbleached cake flour at 120 g as well, so a swap among those three keeps the weight at 480 g even though the crumb changes.

Four cups in ounces, tablespoons and teaspoons

Grams are the cleanest unit here, but recipes still print ounces, tablespoons and fluid ounces, and the last one is where conversions go wrong. At the chart weight, four cups works out as follows.

Those last two rows are volume, not weight. A liquid measuring cup filled to 32 fl oz holds four cups of flour, but that flour weighs 16.9 oz, not 32 oz, because flour is roughly half as dense as water. Read a recipe that lists flour in fluid ounces and it is describing space, not mass.

The 946 mL row explains a storage problem. A one quart jar is 946 mL, so 480 g of flour fills it level with the rim and leaves no room for a scoop or a lid to settle. A 1.5 quart jar or a 2 quart container holds the same flour with the headroom a kitchen needs.

Bread flour at 480 g: same weight, more thirst

Bread flour and all purpose both weigh 120 g per cup, so four cups is 480 g either way. What differs is the protein, roughly one percentage point more in bread flour, and protein is what sets how much water the flour can hold.

A lean dough at 60 percent hydration on 480 g of flour takes 480 x 0.60 = 288 g of water. Push the same flour to 65 percent and the water climbs to 480 x 0.65 = 312 g, a 24 g difference that shows up as a softer, more extensible dough. Bread flour usually wants that 65 percent where all purpose is comfortable at 60, and a strong flour can go to 70 percent, which is 480 x 0.70 = 336 g.

The rule that keeps this straight: hold the flour at 480 g and move the water. Change the flour type and keep the water, and the dough tells you about it within a minute of mixing, either stiff and shaggy or slack and sticky.

Whole wheat complicates the same arithmetic because four cups weighs 452 g rather than 480 g, and the bran absorbs water that white flour leaves free. A whole wheat loaf built on 452 g of flour at 70 percent takes 452 x 0.70 = 316 g of water, close to the 312 g a white dough uses at 65 percent with more flour in it.

Mixing 480 g: 806 g of dough and the bowl that holds it

Once the flour is weighed, the bowl has to hold everything else. A 65 percent dough on 480 g of flour is 480 + 312 = 792 g before salt and yeast, and 9.6 g of salt at 2 percent plus 4.8 g of yeast at 1 percent bring it to about 806 g.

That mass fits comfortably in a 5 quart stand mixer, which most makers rate for roughly 1.5 kg of dough at bread hydration. At 806 g the bowl is a little over half full, which leaves room for the dough to climb the hook during the first mix. A 3.5 quart bowl rated near 1 kg is at the edge, and a hand mixer will stall long before the gluten develops.

Enriched doughs weigh more than the flour and water suggest. Add 96 g of butter at 20 percent of the flour weight and 48 g of sugar at 10 percent and the same batch reaches 806 + 96 + 48 = 950 g, still inside a 5 quart bowl but past what a 3.5 quart one handles without climbing the hook.

A single four cup batch is also easy to mix by hand in a 4 quart bowl, which is why the recipe survives in kitchens without a stand mixer. The bowl needs to be about twice the dough volume, and 806 g of dough at bread hydration takes up a bit under a liter, so a 4 quart bowl at 3.8 L gives it room to double.

A five pound bag is 4.7 batches at 480 g

A five pound bag holds 2,268 g of flour regardless of how it settled in the warehouse. Divide by 480 g and the bag covers 2,268 / 480 = 4.7 batches, which is four full batches plus 348 g left in the corner of the bag.

The filling method changes the count. Dip and sweep at 568 g per batch gives 2,268 / 568 = 4.0 batches, so the fifth bake disappears without a single ingredient changing. Whole wheat at 452 g per batch stretches the same bag to 2,268 / 452 = 5.0 batches.

Read the table as a shopping rhythm rather than a cost exercise. One four cup bake a week uses 480 g, which is 480 / 2,268 = 21 percent of a five pound bag, so a bag lasts a little under five weeks. Two bakes a week and the same bag is gone in sixteen days.

Flour keeps for months in a sealed container, so the batch count matters most when you buy in bulk. A 25 lb sack at 23.6 batches is roughly half a year of weekly baking, and it needs a container that holds 11.3 kg without inviting pantry moths.

Half, double and the 250 mL metric cup at 507 g

Gram weights scale linearly, which is the quiet advantage of writing them down. Half of four cups is 2 cups and 480 / 2 = 240 g, a double batch is 8 cups and 480 x 2 = 960 g, and a batch and a half is 6 cups and 720 g.

The ounce column is the gram figure divided by 28.3495, so 960 / 28.3495 = 33.86, rounded to 33.9. Nothing in the column drifts when the batch changes, which is why a doubled recipe written in grams behaves exactly like the original.

Metric cups are the exception. A 250 mL cup holds 250 / 236.588 = 1.057 times the volume of a US cup, so four metric cups of all purpose flour weigh 4 x 120 x 1.057 = 507 g, which is 27 g more than four US cups. An Australian or European recipe that says four cups means 507 g, not 480 g, and the gap is large enough to firm up a batter.

The converter on this page covers the awkward sizes: type 4.75 and it prints 570 g and 4 3/4 cups, paste a gram weight into the reverse box and it returns cups, and the flour menu swaps the per cup weight for rye, spelt, almond or semolina. Every figure it shows traces back to the tables above.
