How Much Is 8 Ounces of Buttermilk in Milliliters?

8 ounces of buttermilk equals 219.01 ml. 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 × 236.588 = milliliters
  1. Start with 8 ounces of buttermilk
  2. Convert ounces to grams: 8 × 28.35 = 226.80g
  3. 1 cup of buttermilk = 245g
  4. 226.80g ÷ 245g/cup = 0.93 cups × 236.588 = 219.01 milliliters

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

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 219.01 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 8 ounces: 8 × 28.3495 = 226.80g, then 226.80 ÷ 245 = 0.93 cups × 236.588 = 219.01 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: 219.01 ml ÷ 236.588 = 0.925699 cups, then 0.925699 × 245g/cup = 226.80g, then 226.80g ÷ 28.3495 = 8 ounces. Or use the Milliliters to Ounces converter.
