How Much Is 2.66 Ounces of Flaxseed in Cups?
2.66 ounces of flaxseed equals 0.51 cups. Flaxseed has a density of 148g per cup. A lighter ingredient like cocoa powder (86g/cup) would fill even more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 2.66 ounces of flaxseed
- Convert ounces to grams: 2.66 × 28.35 = 75.41g
- 1 cup of flaxseed = 148g
- 75.41g ÷ 148g/cup = 0.51 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Ground and whole flaxseed have different densities. Make sure you are using the form your recipe specifies.

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?
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.
