Formula and Step-by-Step

cups × 114g/cup ÷ 28.3495g/oz = ounces
  1. Start with 143 cups of cake flour
  2. 1 cup of cake flour = 114g
  3. 143 × 114 = 16,302g
  4. Convert grams to ounces: 16,302 ÷ 28.3495 = 575.04 oz

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 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?

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.

Frequently Asked Questions

About 575.04 oz, based on cake flour having a density of 114g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 114 (grams per cup for cake flour), then divide by 28.3495 to convert grams to ounces. For 143 cups: 143 × 114 = 16,302g, then 16,302 ÷ 28.3495 = 575.04 oz.
For the most accurate results, weigh cake 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 114 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 125.4 to 142.5 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 575.04 oz × 28.3495 = 16,302g, then 16,302g ÷ 114 = 143 cups. Or use the Ounces to Cups converter.
