Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 245g/cup × 236.588 = milliliters
  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 × 236.588 = 27.38 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.

Frequently Asked Questions

About 27.38 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 1 ounce: 1 × 28.3495 = 28.35g, then 28.35 ÷ 245 = 0.12 cups × 236.588 = 27.38 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: 27.38 ml ÷ 236.588 = 0.115712 cups, then 0.115712 × 245g/cup = 28.35g, then 28.35g ÷ 28.3495 = 1 ounce. Or use the Milliliters to Ounces converter.
