3 cups of chia seeds weighs 17.25 oz. This is based on chia seeds having a density of 163g per cup. Because cups measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3 cups.
Formula and Step-by-Step
- Start with 3 cups of chia seeds
- 1 cup of chia seeds = 163g
- 3 × 163 = 489g

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