Formula and Step-by-Step

cups × 245g/cup = grams
  1. Start with 1 cup of buttermilk
  2. 1 cup of buttermilk = 245g
  3. 1 × 245 = 245g

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

Mental Math Shortcut

For 1 cup of buttermilk, just remember: 245g. Double it for 2 cups (490g), halve it for a half cup (122.5g).

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.

A cup is a US customary unit of volume equal to 236.588 milliliters or 8 fluid ounces. It is the most common volume measurement in American recipes. One cup can be divided into 16 tablespoons or 48 teaspoons.

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.

Frequently Asked Questions

About 245.00 g, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 245 (grams per cup for buttermilk). For 1 cup: 1 × 245 = 245.00 g.
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: 245.00 g ÷ 245 = 1 cup. Or use the Grams to Cups converter.
