How Much Is 138 Teaspoons of Buttermilk in Grams?
138 teaspoons of buttermilk weighs 704.38 g. This is based on buttermilk having a density of 245g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 138 teaspoons.
Formula and Step-by-Step
- Start with 138 teaspoons of buttermilk
- 1 teaspoon of buttermilk = 5.10g
- 138 × 5.10 = 704.38g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units
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.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
