How Much Is 3.5 Ounces of Flaxseed in Cups?
3.5 ounces of flaxseed equals 0.67 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 3.5 ounces of flaxseed
- Convert ounces to grams: 3.5 × 28.35 = 99.22g
- 1 cup of flaxseed = 148g
- 99.22g ÷ 148g/cup = 0.67 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.
