How Much Is 0.15 Cups of Buttermilk in Ounces?
Converting 0.15 cups of buttermilk to ounces gives 1.30 oz. One cup of buttermilk weighs 245g, so 0.15 cups is 0.15 × 245 = 36.75g (1.30 oz). This conversion is specific to buttermilk because each ingredient has a different density.
Formula and Step-by-Step
- Start with 0.15 cups of buttermilk
- 1 cup of buttermilk = 245g
- 0.15 × 245 = 36.75g
- Convert grams to ounces: 36.75 ÷ 28.3495 = 1.30 oz
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 Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
