Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 245g/cup × 16 = tablespoons
  1. Start with 15.38 ounces of buttermilk
  2. Convert ounces to grams: 15.38 × 28.35 = 436.02g
  3. 1 cup of buttermilk = 245g
  4. 436.02g ÷ 245g/cup = 1.78 cups × 16 = 28.47 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?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

What is a Tablespoon?

One tablespoon holds about 15 milliliters. There are 16 tablespoons in a cup and 3 teaspoons in a tablespoon. In baking, tablespoon measurements are used for butter, oil, honey, and other ingredients where a full cup would be too much.

Frequently Asked Questions

About 28.47 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 15.38 ounces: 15.38 × 28.3495 = 436.02g, then 436.02 ÷ 245 = 1.78 cups × 16 = 28.47 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: 28.47 tbsp ÷ 16 = 1.77966 cups, then 1.77966 × 245g/cup = 436.02g, then 436.02g ÷ 28.3495 = 15.38 ounces. Or use the Tablespoons to Ounces converter.
