There are about 1.9 cups in a pound of Buttermilk. Buttermilk weighs 245 g per cup (poured), so a pound — 453.59 g — divides to 1.85 cups. Tangy cultured milk that tenderises batters and activates baking soda. Pancakes, biscuits, fried chicken and ranch dressing. Every figure on this page is approximate, because a cup measures volume and the weight depends on how the ingredient settles and how it was measured; when the amount matters — a cake, a sauce that must set, a dough that must rise — weigh the Buttermilk on a kitchen scale instead of trusting the cup. This page gives you the full table for a pound and beyond, worked examples from real recipes, the method behind the figure, and the mistakes that catch people out.

How many cups in a pound of Buttermilk?

A pound of Buttermilk is about 1.9 cups (1.85 cups, to be exact). The table below covers a quarter of a pound up to ten pounds, so you can read off whatever your recipe or your bulk buy calls for without doing the division yourself. If your recipe lists Buttermilk in grams, the same table works in reverse: find the grams and read across to the cups.

Amount Cups Grams Tablespoons Millilitres
0.25 lb 0.46 113 7 110
0.5 lb 0.93 227 15 219
0.75 lb 1.39 340 22 329
1 lb 1.85 454 30 438
2 lb 3.70 907 59 876
5 lb 9.26 2268 148 2190
10 lb 18.51 4536 296 4380

The tablespoons column is the useful one for small amounts: a pound of Buttermilk is about 30 tablespoons, and a single tablespoon weighs about 15.3 g. Use the pounds to grams converter if your recipe lists a different weight, and the cups to grams converter if you need the figure for a single cup of buttermilk.

How the maths works

The conversion is a single division: one pound is 453.59 g, and one cup of Buttermilk weighs 245 g, so 453.59 ÷ 245 = 1.85 cups. Going the other way, one cup of Buttermilk weighs 245 g, which is 0.54 lb, and one tablespoon weighs about 15.3 g while one teaspoon weighs about 5.10 g. To get any number of cups, weigh that many times 245 g: two cups is 490 g, three cups is 735 g, and half a cup is 122 g. In volume terms, a pound of Buttermilk is about 438 ml, since one US cup is 236.6 ml. Remember that the cup is a volume and the pound is a weight, so this maths only works because we know the density of Buttermilk; the same pound of a different ingredient would be a different number of cups entirely.

Worked examples

The examples below use real recipes, with the cups and the grams side by side so you can follow the maths in context. Each one also notes where the cup is good enough and where the scale earns its keep.

Brining fried chicken for eight

Brining fried chicken for eight needs 2 cups of Buttermilk — about 490 g — poured over 8 chicken pieces with salt and hot sauce, left overnight. Two cups is just over a pound, so a quart carton covers this brine with a little left for the dredge; the acid in buttermilk is what tenderises the meat.

A batch of buttermilk biscuits

A batch of buttermilk biscuits needs 1 cup of Buttermilk — about 245 g — stirred into 2 cups of flour with cold butter for 12 biscuits. Keep the buttermilk cold and handle the dough as little as possible; warm buttermilk melts the butter pieces that make biscuits flaky.

Buttermilk pancakes for a family breakfast

Buttermilk pancakes for a family breakfast need 1 1/2 cups of Buttermilk — about 368 g — mixed with flour, eggs and baking soda for about 16 pancakes. The soda needs the buttermilk's acid to work, so do not swap in plain milk here without adding a spoonful of lemon juice or vinegar.

How the figure was measured

The weight figure on this page comes from USDA: Buttermilk weighs 245 g per cup, measured poured, and that figure carries high confidence in CookScale's 120-ingredient table. USDA lists cultured buttermilk at about 245 g per cup; King Arthur rounds it to 227 g. All weights are per US cup (236.6 ml), and every cup-based result on this page is approximate, because a cup measures volume while the weight depends on how the ingredient settles, how fresh it is, and how it was measured. When the amount matters — a cake, a sauce that must set, a dough that must rise — weigh the Buttermilk on a kitchen scale instead of trusting the cup. Read more about this ingredient on the Buttermilk hub, which covers its weight, its measures, its storage and its substitutes in one place.

How to measure it

Spoon or pour Buttermilk into the right measure for its texture: liquids go in a liquid jug read at eye level, while thick dairy like Buttermilk is best weighed on a scale or spooned into a dry cup and levelled. Never pack thick dairy down — pressing it into the cup squeezes out air and whey and fits far more weight into the same volume. A tablespoon of Buttermilk weighs about 15.3 g, so for small amounts a spoon is more accurate than a cup.

Practical guidance

Dairy is perishable, so a pound of it needs using within days rather than weeks — plan the recipes before you open the tub, not after. Refrigerate; use within 2 weeks. Shake the carton before measuring; buttermilk separates on standing and the first pour is thinner than the last. If you buy in bulk for a big cook, freeze what you will not use within the week, but remember that freezing changes the texture of most dairy: it is fine for cooking and baking, less good for eating fresh.

Why recipes ask for a pound of Buttermilk

Buttermilk is sold in cartons by volume, but baking recipes scaled up for a bakery or a church supper often list it by weight, and a cook doubling a biscuit recipe needs to know how far a pound stretches. A pound is just under two cups, so the standard quart carton, at four cups, holds a little over two pounds — enough for two full batches of biscuits with a splash left for pancakes.

Buying and storing a pound of Buttermilk

A pound of dairy is a single tub or carton in most cases, and the price difference between the small and large sizes is usually small — buy the size you will actually finish before the use-by date. For a big cook, two pound tubs are often cheaper than one two-pound tub, and they keep better once opened.

Frequently asked questions

How many tablespoons are in a pound of Buttermilk?

About 30 tablespoons. A pound of Buttermilk is about 1.85 cups, and there are 16 tablespoons in a cup, so 1.85 × 16 is about 30. A single tablespoon weighs about 15.3 g.

How much does a cup of Buttermilk weigh in ounces?

About 8.6 oz. One cup of Buttermilk weighs 245 g, and there are 28.35 g in an ounce, so 245 ÷ 28.35 is 8.6 oz. A pound (16 oz) is therefore about 1.85 cups.

Can I swap Buttermilk for another dairy by weight?

Only if you use the right figure for each one. Dairy products sit close together — milk is 244 g per cup and buttermilk 245 g — but cream cheese is 232 g and ricotta 246 g, so swapping by cups is safer than swapping by weight. When in doubt, weigh each ingredient against its own figure.

Does low-fat Buttermilk weigh the same per cup?

Not exactly. Low-fat dairy has more water and less fat, so it is marginally heavier per cup than the full-fat product in this table. The difference is small — a few grams per cup — but if the amount matters, weigh the low-fat version on a scale rather than using the full-fat figure.

Can I make buttermilk from milk and lemon juice?

Yes — add one tablespoon of lemon juice or white vinegar to a cup of milk and wait ten minutes until it thickens slightly. It works for pancakes and biscuits, though it lacks the cultured tang of real buttermilk, so for fried chicken brine the real thing is worth buying.
