Convert Cups to Grams: Chia Seeds
Convert cups of chia seeds to grams with this complete reference table. 1 cup of chia seeds = 160g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because chia seeds density can vary by measuring technique.
Chia Seeds Cups to Grams Table
| Cups | Grams |
|---|---|
| 1/8 cup | 20g |
| 1/4 cup | 40g |
| 1/3 cup | 53.3g |
| 1/2 cup | 80g |
| 2/3 cup | 106.7g |
| 3/4 cup | 120g |
| 1 cup | 160g |
| 1 1/4 cups | 200g |
| 1 1/2 cups | 240g |
| 2 cups | 320g |
| 3 cups | 480g |
| 4 cups | 640g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Chia seeds: 1 cup = 160g. Very small and dense — pack tightly. Absorb up to 12x their weight in water forming a gel. 1 tablespoon chia + 3 tablespoons water = 1 egg substitute. Black and white chia seeds are nutritionally identical. USDA FDC 170554.
About Chia Seeds Density
The density of chia seeds determines how much it weighs per unit of volume. At 0.667g/ml, 1 US cup (240ml) of chia seeds weighs 160g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
Frequently Asked Questions
How many grams is 1 cup of chia seeds?
1 cup of chia seeds weighs 160 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).
How many grams is 1/2 cup of chia seeds?
1/2 cup of chia seeds weighs 80 grams.
How many grams is 1/4 cup of chia seeds?
1/4 cup of chia seeds weighs 40 grams.
Does measuring technique affect the weight of chia seeds?
Yes. Sifted chia seeds can weigh up to 20% less than packed or scooped. The USDA standard (spooned-and-leveled) of 160g/cup is the most reliable baseline.
