Measuring Tip
Humidity affects bread flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.
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.

The most accurate way is to weigh bread flour on a kitchen scale. If you are measuring by volume, sift or whisk the flour first to break up clumps, then spoon it into the measuring cup and level it off. Do not scoop directly from the bag, which compacts the flour and can increase the weight by 20-30%.
Close, but not exactly. The cups to ounces conversion for bread flour may vary slightly between brands depending on moisture content and how the ingredient is measured.
Weighing is more consistent than volume measuring. A cup of bread flour can vary by 10-20% depending on how it's scooped, packed, or leveled. Weighing gives the same result every time, which is especially important in baking where precision affects texture and rise.
