How Much Is 21.35 Grams of Butter in Teaspoons?
21.35 grams of butter equals 4.51 tsp. Butter has a density of 227g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 21.35 grams of butter
- 1 cup of butter = 227g
- 21.35g ÷ 227g/cup = 0.09 cups × 48 = 4.51 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Softened butter and melted butter measure differently by volume. Melted butter settles with no air pockets, giving a slightly higher weight per cup.

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.
