How Much Is 1 Ounce of Buttermilk in Tablespoons?
1 ounce of buttermilk equals 1.85 tbsp. Buttermilk has a density of 245g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 1 ounce of buttermilk
- Convert ounces to grams: 1 × 28.35 = 28.35g
- 1 cup of buttermilk = 245g
- 28.35g ÷ 245g/cup = 0.12 cups × 16 = 1.85 tablespoons
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.
