How Much Is 18.5 Grams of Chia Seeds in Teaspoons?
18.5 grams of chia seeds equals 5.45 tsp. Chia seeds has a density of 163g per cup. Because grams measure weight and teaspoons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 18.5 grams of chia seeds
- 1 cup of chia seeds = 163g
- 18.5g ÷ 163g/cup = 0.11 cups × 48 = 5.45 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
