Formula and Step-by-Step

teaspoons × 3.40g/tsp = grams
  1. Start with 18 teaspoons of chia seeds
  2. 1 teaspoon of chia seeds = 3.40g
  3. 18 × 3.40 = 61.13g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Ground and whole chia seeds have different densities. Make sure you are using the form your recipe specifies.

Understanding the Units

What is a Teaspoon?

In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 61.13 g, based on chia seeds having a density of 163g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 3.40 (grams per teaspoon for chia seeds). For 18 teaspoons: 18 × 3.40 = 61.13 g.
For the most accurate results, weigh chia seeds on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 61.13 g ÷ 3.40 = 18 teaspoons. Or use the Grams to Teaspoons converter.
