Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 102g/cup = cups
  1. Start with 12 ounces of rye flour
  2. Convert ounces to grams: 12 × 28.35 = 340.19g
  3. 1 cup of rye flour = 102g
  4. 340.19g ÷ 102g/cup = 3.34 cups

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

Understanding the Units

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

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.

Frequently Asked Questions

About 3.34 cups, based on rye flour having a density of 102g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 102 (grams per cup). For 12 ounces: 12 × 28.3495 = 340.19g, then 340.19 ÷ 102 = 3.34 cups.
For the most accurate results, weigh rye 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.
Yes, quite a bit. If you spoon the flour into your measuring cup and level it off, you will get about 102 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 112.2 to 127.5 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 3.34 cups × 102g/cup = 340.19g, then 340.19g ÷ 28.3495 = 12 ounces. Or use the Cups to Ounces converter.
