How Much Is 102.9 Grams of Buttermilk in Teaspoons?
102.9 grams of buttermilk equals 20.16 tsp. Buttermilk has a density of 245g 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 102.9 grams of buttermilk
- 1 cup of buttermilk = 245g
- 102.9g ÷ 245g/cup = 0.42 cups × 48 = 20.16 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For liquids, place your measuring spoon on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

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.
