Grams to cups: buttermilk

Working the other way — a recipe in grams, and cups are what you have in the drawer:

Grams of buttermilk Cups (approx.)
50 g ⅙ cups
100 g ⅜ cups
125 g ½ cups
200 g ⅚ cups
250 g 1 cups
500 g 2.04 cups

Where this number comes from

Most of our weights are the King Arthur Baking chart figure, unchanged. This one is not, and it is worth saying why: Physical density: ~1.035 g/ml. King Arthur lists every liquid at a flat 227 g.

We would rather publish the number your scale will agree with and show our reasoning than quote a familiar chart that rounds the physics away. Every value we don't depart on is locked to the chart by a test, so this list stays short and deliberate — you can read all of them on the methodology page.
