Buttermilk is a tangy, slightly acidic dairy liquid used in pancakes, cakes, quick breads, and marinades. One metric cup (250 ml) weighs 255 g (8.99 oz). Despite its name, it contains very little butter: modern buttermilk is made by culturing low-fat milk with bacterial cultures.

Recipes often call for buttermilk by volume, but measuring by weight gives more consistent results, especially when scaling. This page converts buttermilk between grams, cups, millilitres, fluid ounces, and more.

Buttermilk Substitute Calculator

Milk is thinner and less acidic than buttermilk. To substitute, stir 1 tablespoon of lemon juice or white vinegar into 1 cup of milk, then let it sit for a few minutes until it curdles slightly. See our Milk converter.

Lemon juice stirred into regular milk makes a quick buttermilk substitute. Use 1 tablespoon of lemon juice per 1 cup of milk, stir, and let it curdle for a few minutes before using. See our Lemon Juice converter.

Plain yoghurt is thicker than buttermilk but shares the tang and acidity. To use yoghurt in place of buttermilk, stir 2 to 3 tablespoons of milk into 1 cup of yoghurt to match the pourable texture. See our Plain Yoghurt converter.

Sour cream is thick and spoonable, while buttermilk is thin and pourable. To use sour cream in place of buttermilk, thin it with milk in a 3:1 ratio until pourable; the tang and acidity stay close. See our Sour Cream converter.
