How Much Is 21 Grams of Onion Powder in Teaspoons?
21 grams of onion powder equals 9.00 tsp. Onion powder has a density of 112g 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 grams of onion powder
- 1 cup of onion powder = 112g
- 21g ÷ 112g/cup = 0.19 cups × 48 = 9.00 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For the most accurate results, weigh onion powder on a kitchen scale. At small quantities, even slight over-measuring can overpower a dish.

Understanding the Units
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.
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.
