About the Cups to Ounces — Whole Wheat Flour
Whole wheat contains bran and germ, which are bulkier and lighter than endosperm, so a cup weighs less than plain flour despite feeling coarser. It also absorbs more liquid as it sits, which is why whole wheat doughs stiffen noticeably during a rest. Substituting it one-for-one for white flour usually needs 1–2 extra tablespoons of liquid per cup. The figure this page works from is 113 g per US cup, the spooned-and-levelled weight recorded by King Arthur Baking and the USDA food database. Converting us cup to ounce for whole wheat flour, the amounts that come up most often are: 1/4 us cup = 0.996 ounce; 1/3 us cup = 1.33 ounce; 1/2 us cup = 1.99 ounce; 2/3 us cup = 2.66 ounce; 3/4 us cup = 2.99 ounce; 1 us cup = 3.99 ounce; 1 1/2 us cup = 5.98 ounce; 2 us cup = 7.97 ounce; 3 us cup = 12 ounce.
What people use it for
- Following a US recipe with a kitchen scale instead of cup measures.
- Scaling a recipe up or down without compounding measuring error.
- Converting a European recipe written in grams into cups.

The maths behind it
This tool uses ounce = us cup × 3.9859577003, derived from whole wheat flour weighing 113 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.
Whole wheat contains bran and germ, which are bulkier and lighter than endosperm, so a cup weighs less than plain flour despite feeling coarser. It also absorbs more liquid as it sits, which is why whole wheat doughs stiffen noticeably during a rest.
Where this tool stops
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent.
Frequently asked questions
Why did my bread come out dry when I swapped in whole wheat?
Because the bran absorbs more water. Swap by weight, add a little extra liquid, and let the dough rest twenty minutes before kneading so the bran has time to hydrate.
Why does a cup of whole wheat flour not weigh the same as a cup of water?
Because a cup measures volume and a scale measures weight, and the two only agree for water. Whole wheat flour has its own density — 113 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
Quite a lot, though less dramatically than white flour. The bran makes whole wheat bulkier and more irregular, so it does not pack as tightly — a scooped cup runs perhaps 10–15% over the 113 g here rather than 20%. The bigger variable with whole wheat is how long it has sat absorbing liquid, not how you filled the cup.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.6 ml, a metric cup is 250 ml and an old UK cup is 284 ml. These pages use the US cup, because that is what US recipes mean.

Where does the Cups to Ounces — Whole Wheat Flour stop being reliable?
