How Much Is 21.28 Grams of Cinnamon in Teaspoons?
21.28 grams of cinnamon equals 7.98 tsp. Cinnamon has a density of 128g per cup. A lighter ingredient like cocoa powder (86g/cup) would fill even more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 21.28 grams of cinnamon
- 1 cup of cinnamon = 128g
- 21.28g ÷ 128g/cup = 0.17 cups × 48 = 7.98 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Ground spices like cinnamon settle and compact during storage. Stir or fluff before measuring by volume for a consistent amount.

Understanding the Units
What is a Gram?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
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.
