Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 245g/cup × 236.588 = milliliters
  1. Start with 5 ounces of buttermilk
  2. Convert ounces to grams: 5 × 28.35 = 141.75g
  3. 1 cup of buttermilk = 245g
  4. 141.75g ÷ 245g/cup = 0.58 cups × 236.588 = 136.88 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?

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.

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.

Frequently Asked Questions

About 136.88 ml, 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 236.588 to get milliliters. For 5 ounces: 5 × 28.3495 = 141.75g, then 141.75 ÷ 245 = 0.58 cups × 236.588 = 136.88 ml.
For the most accurate results, weigh buttermilk on a kitchen scale. If measuring by volume, use a liquid measuring cup 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: 136.88 ml ÷ 236.588 = 0.578562 cups, then 0.578562 × 245g/cup = 141.75g, then 141.75g ÷ 28.3495 = 5 ounces. Or use the Milliliters to Ounces converter.
