Formula and Step-by-Step

teaspoons × 5.10g/tsp = grams
  1. Start with 1 teaspoon of buttermilk
  2. 1 teaspoon of buttermilk = 5.10g
  3. 1 × 5.10 = 5.10g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Mental Math Shortcut

For 1 teaspoon of buttermilk, just remember: 5.10g. Double it for 2 teaspoons (10.21g), halve it for a half teaspoon (2.55g).

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?

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.

Frequently Asked Questions

About 5.10 g, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 5.10 (grams per teaspoon for buttermilk). For 1 teaspoon: 1 × 5.10 = 5.10 g.
For the most accurate results, weigh buttermilk on a kitchen scale. If measuring by volume, use a liquid measuring spoon on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of buttermilk changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 5.10 g ÷ 5.10 = 1 teaspoon. Or use the Grams to Teaspoons converter.
