Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 163g/cup = cups
  1. Start with 18.2 ounces of chia seeds
  2. Convert ounces to grams: 18.2 × 28.35 = 515.96g
  3. 1 cup of chia seeds = 163g
  4. 515.96g ÷ 163g/cup = 3.17 cups

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

Measuring Tip

For the most consistent results, weigh chia seeds on a kitchen scale. Small seeds are easy to over-measure by volume.

Understanding the Units

What is an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

Frequently Asked Questions

About 3.17 cups, 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.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 163 (grams per cup). For 18.2 ounces: 18.2 × 28.3495 = 515.96g, then 515.96 ÷ 163 = 3.17 cups.
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.
Reverse the conversion: 3.17 cups × 163g/cup = 515.96g, then 515.96g ÷ 28.3495 = 18.2 ounces. Or use the Cups to Ounces converter.
