Formula and Step-by-Step

cups × 128g/cup = grams
  1. Start with 3.91 cups of coconut flour
  2. 1 cup of coconut flour = 128g
  3. 3.91 × 128 = 500.48g

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

Measuring Tip

Coconut flour clumps when stored. Sift or whisk it before measuring for consistent results.

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 a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 500.48 g, 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.
Multiply the number of cups by 128 (grams per cup for coconut flour). For 3.91 cups: 3.91 × 128 = 500.48 g.
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: 500.48 g ÷ 128 = 3.91 cups. Or use the Grams to Cups converter.
