Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 120g/cup = cups
  1. Start with 3.51 ounces of self-rising flour
  2. Convert ounces to grams: 3.51 × 28.35 = 99.51g
  3. 1 cup of self-rising flour = 120g
  4. 99.51g ÷ 120g/cup = 0.83 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?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

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 0.83 cups, based on self-rising flour having a density of 120g 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 120 (grams per cup). For 3.51 ounces: 3.51 × 28.3495 = 99.51g, then 99.51 ÷ 120 = 0.83 cups.
For the most accurate results, weigh self-rising 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 120 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 132 to 150 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 0.83 cups × 120g/cup = 99.51g, then 99.51g ÷ 28.3495 = 3.51 ounces. Or use the Cups to Ounces converter.
