Buttermilk Measurement Converter
Use the tool below to convert buttermilk from the measurements in your recipe to the measurements that you need.
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.

Frequently Asked Questions
- Are buttermilk and cultured buttermilk the same thing?
- Yes. Cultured buttermilk is another name for buttermilk, so they are the same ingredient and measure identically. A cup of buttermilk weighs 255 grams under either name, and every conversion on this page holds whichever name your recipe uses. Recipes swap the two freely, so you can follow either without changing quantities or weighing any differently.
- What is 0.25 cups of buttermilk in tablespoons?
- 0.25 cups of buttermilk is 4.17 tablespoons. This is the same for any ingredient, since cups and tablespoons are both volume units and do not depend on what you are measuring. One cup is about 16.67 tablespoons, so 0.5 cups is 8.33 tablespoons. Use the volume converter to switch between cups, tablespoons, teaspoons, and millilitres for any amount. Open the volume converter
- How much does a cup of buttermilk weigh?
- 1 cup of buttermilk in grams is 255 grams. The ratio is fixed, so 2 cups is 510 grams and half a cup is 127.5 grams. Weighing buttermilk by the cup is the most common way to measure it for baking. The chart above this FAQ lists the cup amounts recipes call for, and the converter at the top handles anything between them.

Plain Yoghurt
Plain yoghurt shares the tang but is thicker. Thinning with milk matches the pourable texture buttermilk gives pancakes and quick breads. See our Plain Yoghurt converter.
Sour Cream
Same acidity, but thicker. Thin with milk to a pourable consistency. Works in cake batters and marinades. See our Sour Cream converter.
Milk
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
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.
