Chia Seeds:
Grams to Cups
By Stefan Ulrich · Last updated
Dry chia seeds weigh 170 grams per cup — denser than most seeds due to their tiny, round shape that packs with minimal air gaps. But the measurement that matters most for chia is the soaked weight: chia seeds absorb up to 12 times their weight in liquid.

About Chia Seeds
When chia seeds absorb liquid, they form a gel-like coating that dramatically increases their volume and weight. One tablespoon of dry chia seeds (11 g) mixed with 3 tablespoons of water produces about 50 g of chia gel — a popular egg substitute in vegan baking.
The egg substitute ratio: 1 tablespoon chia seeds + 3 tablespoons water = 1 egg equivalent. Let the mixture sit for 5–10 minutes until it forms a thick gel. This works best in recipes where eggs serve as binders (cookies, muffins, pancakes) rather than as leaveners (soufflés, angel food cake).
For chia pudding, the standard ratio is 3 tablespoons chia seeds (33 g) per cup of liquid (240 ml). This produces a thick, tapioca-like pudding after 2+ hours of refrigeration. For a thinner consistency, reduce to 2 tablespoons per cup.
Ground chia seeds weigh about 130 g/cup (less dense due to the broken structure). They absorb liquid faster than whole seeds but produce a less distinct texture. In baked goods, ground chia distributes more evenly.
Tips for measuring Chia Seeds
- 1 tbsp dry chia + 3 tbsp water = 1 egg substitute. Wait 5–10 min for gel.
- Chia pudding: 3 tbsp (33 g) per cup of liquid, refrigerate 2+ hours.
- Ground chia: ~130 g/cup, absorbs faster but different texture.
- Store dry chia seeds in a cool, dark place — shelf life is 2+ years.
Common mistakes
- Not waiting long enough for gel formation — undermines binding and thickening
- Using chia as an egg substitute in recipes that rely on eggs for volume/lift

- 1 cup of Chia Seeds weighs 170 grams — the standard used in most American recipes. Use the converter above for any other amount.
- How many grams is 1 tablespoon of Chia Seeds?
- 1 tablespoon of Chia Seeds weighs about 11 grams. The full table above lists every common cup fraction.
- What's the most common mistake when measuring Chia Seeds?
- Not waiting long enough for gel formation — undermines binding and thickening. Weighing on a kitchen scale avoids it entirely.
- Should Chia Seeds be measured cooked or dry?
- These values are for dry, uncooked chia Seeds. Cooked weights differ greatly because of absorbed water.
