How Much Is 1 Teaspoon of Buttermilk in Ounces?
1 teaspoon of buttermilk weighs 0.18 oz. This is based on buttermilk having a density of 245g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1 teaspoon.
Formula and Step-by-Step
- Start with 1 teaspoon of buttermilk
- 1 teaspoon of buttermilk = 5.10g
- 1 × 5.10 = 5.10g
- Convert grams to ounces: 5.10 ÷ 28.3495 = 0.18 oz
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 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 an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
