Chia seeds weigh about 170 grams per cup and have the unusual property of absorbing many times their weight in liquid, forming a gel. That gel sets chia puddings and works as a vegan egg replacer. They are measured the same dry, but their volume balloons once wet.

How to measure chia seeds accurately
For the most reliable baking results, weigh chia seeds on a kitchen scale rather than scooping by volume. One US cup of chia seeds weighs about 170 grams (6 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts chia seeds and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Mix 1 tablespoon of chia seeds with 3 tablespoons of water and let it sit 10 minutes to make a 'chia egg' that binds vegan bakes.
