Grams to Cups: Buttermilk
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for buttermilk. One cup of buttermilk weighs about 245 grams, which works out to a density of 1.04 g/ml. From there, half a cup is roughly 123 g, a quarter cup about 61 g, and one tablespoon about 15 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of buttermilk does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of buttermilk, taken from the USDA FoodData Central database, rather than a one-size-fits-all figure.

How to measure buttermilk accurately
Measure buttermilk in a clear liquid measuring cup on a flat surface and read the line at eye level; looking from above is misleading because of surface tension. For solid fats like butter, use the markings on the wrapper or the water-displacement method.
When you need maximum accuracy, weigh the liquid in grams — a scale is more exact than any cup.
