Formula and Step-by-Step

grams ÷ 245g/cup × 236.588 = milliliters
  1. Start with 258.89 grams of buttermilk

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 a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

What is a Milliliter?

Most kitchen measuring cups outside the US are marked in milliliters. A standard metric cup is 250 ml. When converting American recipes, 1 US cup = 236.588 ml.

Frequently Asked Questions

About 250.00 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.
Divide the grams by 245 (grams per cup) to get cups, then multiply by 236.588 to get milliliters. For 258.89 grams: 258.89 ÷ 245 = 1.06 cups × 236.588 = 250.00 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: 250.00 ml ÷ 236.588 = 1.05669 cups, then 1.05669 × 245g/cup = 258.89g. Or use the Milliliters to Grams converter.
