Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 245g/cup × 236.588 = milliliters

Start with 2.1 ounces of buttermilk
Convert ounces to grams: 2.1 × 28.35 = 59.53g
1 cup of buttermilk = 245g
59.53g ÷ 245g/cup = 0.24 cups × 236.588 = 57.49 milliliters

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 Milliliter?

Milliliters measure volume and are used worldwide for cooking and baking. For water at room temperature, 1 ml weighs approximately 1 gram, but this relationship does not hold for other ingredients.
