Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

About 5.52 oz, based on all-purpose flour having a density of 125.16g per cup. The exact amount depends on how the ingredient is measured and the specific product.

What is the formula for converting cups of all-purpose flour to ounces? expand_more

How do I measure all-purpose flour accurately? expand_more

For the most accurate results, weigh all-purpose flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring cup and level off. Do not scoop directly from the bag.

Does the measurement method affect how much all-purpose flour weighs per cup? expand_more

Yes, quite a bit. If you spoon the flour into your measuring cup and level it off, you will get about 125.16 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 137.68 to 156.45 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.

How do I convert ounces of all-purpose flour back to cups? expand_more

Reverse the conversion: 5.52 oz × 28.3495 = 156.45g, then 156.45g ÷ 125.16 = 1.25 cups. Or use the Ounces to Cups converter.
