Formula and Step-by-Step

cups × 163g/cup ÷ 28.3495g/oz = ounces
  1. Start with 1 cup of chia seeds
  2. 1 cup of chia seeds = 163g
  3. 1 × 163 = 163g
  4. Convert grams to ounces: 163 ÷ 28.3495 = 5.75 oz

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

Measuring Tip

Frequently Asked Questions

About 5.75 oz, based on chia seeds having a density of 163g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 163 (grams per cup for chia seeds), then divide by 28.3495 to convert grams to ounces. For 1 cup: 1 × 163 = 163g, then 163 ÷ 28.3495 = 5.75 oz.
For the most accurate results, weigh chia seeds on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
