How Much Is 1.5 Cups of Chia Seeds in Ounces?
1.5 cups of chia seeds weighs 8.62 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 1.5 cups.
Formula and Step-by-Step
- Start with 1.5 cups of chia seeds
- 1 cup of chia seeds = 163g
- 1.5 × 163 = 244.5g
- Convert grams to ounces: 244.5 ÷ 28.3495 = 8.62 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
