Measuring Chia Seeds Accurately

Why weight matters: 1 1/2 cups of chia seeds can weigh anywhere from 204g to 288g depending on how you measure it. The USDA standard is 240g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.

About chia seeds density: 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 1½ Cups as a Measurement

1 1/2 cups = 24 tablespoons = 360ml. This is the standard flour amount for a dozen standard-size cookies or a single-layer 8-inch cake. It bridges the gap between single-cup and double-cup recipe scales.

One and a half cups appears most often in cookie dough recipes (flour), quick bread recipes (oats or mix-ins), and pasta sauce recipes (liquid ingredients). It equals 360ml or 12 fluid ounces.
