Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 128g/cup = cups
  1. Start with 1 ounce of coconut flour
  2. Convert ounces to grams: 1 × 28.35 = 28.35g
  3. 1 cup of coconut flour = 128g
  4. 28.35g ÷ 128g/cup = 0.22 cups

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

Measuring Tip

Coconut flour absorbs 3-4x more liquid than wheat flour. When substituting, use about 1/4 to 1/3 the amount and add extra liquid or eggs.

Understanding the Units

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

What is a Cup?

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

Frequently Asked Questions

About 0.22 cups, based on coconut flour having a density of 128g 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 128 (grams per cup). For 1 ounce: 1 × 28.3495 = 28.35g, then 28.35 ÷ 128 = 0.22 cups.
For the most accurate results, weigh coconut 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 128 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 140.8 to 160 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 0.22 cups × 128g/cup = 28.35g, then 28.35g ÷ 28.3495 = 1 ounce. Or use the Cups to Ounces converter.
