How many gram is 1 ounce of whole wheat flour?

1 ounce of whole wheat flour weighs approximately 28 gram. This is based on a density of 0.51 g/ml for whole wheat flour.

How do I measure whole wheat flour accurately?

For accurate whole wheat flour measurement, spoon the flour into your measuring cup and level it off with a knife. Don't scoop directly from the bag, as this compacts the flour and gives you more than intended.

Why should I weigh whole wheat flour instead of using cups?

Weighing whole wheat flour gives more consistent results than volume measurements. A cup of whole wheat flour can vary by 10-20% depending on how it's measured (spooned vs scooped). Professional bakers always weigh ingredients for this reason.

Why does whole wheat flour have a specific cup-to-gram conversion?

Whole Wheat Flour has a density of 0.51 g/ml, meaning each milliliter weighs 0.51 grams. Different ingredients have different densities—for example, flour is lighter than sugar—which is why each needs its own conversion factor.
