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

(ounces × 28.35g/oz) ÷ 245g/cup × 16 = tablespoons
  1. Start with 1 ounce of buttermilk
  2. Convert ounces to grams: 1 × 28.35 = 28.35g
  3. 1 cup of buttermilk = 245g
  4. 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.

Understanding the Units

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.

What is a Tablespoon?

Tablespoon sizes differ by country. A US tablespoon is 14.787 ml, close to the 15 ml metric standard used in most countries. An Australian tablespoon is 20 ml, about 35% larger than US. An imperial tablespoon is 17.758 ml. If your recipe comes from Australia, the larger tablespoon size can make a real difference.

Frequently Asked Questions

About 1.85 tbsp, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 245 (grams per cup), then multiply by 16 to get tablespoons. For 1 ounce: 1 × 28.3495 = 28.35g, then 28.35 ÷ 245 = 0.12 cups × 16 = 1.85 tbsp.
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: 1.85 tbsp ÷ 16 = 0.115712 cups, then 0.115712 × 245g/cup = 28.35g, then 28.35g ÷ 28.3495 = 1 ounce. Or use the Tablespoons to Ounces converter.
