How Many Cups in a Pound of Baking Powder?

There are about 2.4 cups in a pound of Baking Powder. Baking Powder weighs 192 g per cup (spooned and levelled), so a pound — 453.59 g — divides to 2.36 cups. Baking soda plus cream of tartar; double-acting, needs only moisture and heat. Leavening cakes, pancakes and quick breads. 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 Baking Powder 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.

Why recipes ask for a pound of Baking Powder

Baking powder is sold by weight in tins, while recipes call for teaspoons and tablespoons, so the pound question is for the cook scaling up for a bake sale or a café. A pound is about two and a third cups, or roughly 113 teaspoons, which covers a great many pancake breakfasts before it runs out.

How many cups in a pound of Baking Powder?

A pound of Baking Powder is about 2.4 cups (2.36 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 Baking Powder 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	0.59	113	9	140
0.5 lb	1.18	227	19	279
0.75 lb	1.77	340	28	419
1 lb	2.36	454	38	559
2 lb	4.72	907	76	1118
5 lb	11.81	2268	189	2795
10 lb	23.62	4536	378	5590

The tablespoons column is the useful one for small amounts: a pound of Baking Powder is about 38 tablespoons, and a single tablespoon weighs about 12.0 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 baking powder.

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.

Pancakes for a family breakfast

Pancakes for a family breakfast need 2 tablespoons of Baking Powder — about 24 g — two tablespoons in a batter for about 20 pancakes. Two tablespoons is about 24 g; baking powder is double-acting, so it lifts once when wet and again in the heat, which is why pancakes stay fluffy.

A Victoria sponge for a party

A Victoria sponge for a party needs 1.5 tablespoons of Baking Powder — about 18 g — folded into the batter for two layers. A tablespoon and a half is about 18 g; fold it in gently at the end, since beating the batter after adding it knocks the air out.

Biscuits for a Sunday lunch

Biscuits for a Sunday lunch need 1 tablespoon of Baking Powder — about 12 g — one tablespoon in a dough for 12 fluffy biscuits. One tablespoon is about 12 g; cold butter and a hot oven matter more than the exact spoonful, but too much baking powder leaves a metallic taste.

How to measure it

Spoon Baking Powder into a dry measuring spoon and level it with a knife — never scoop the spoon through the tin, and never heap it. Leavening is the one ingredient where a careless spoonful changes the outcome: too much leaves a bitter or metallic taste and can make a cake rise and then collapse. One teaspoon of Baking Powder weighs about 4.00 g, so for large batches weigh it rather than counting spoonfuls.

How the figure was measured

The weight figure on this page comes from King Arthur Baking: Baking Powder weighs 192 g per cup, measured spooned and levelled, and that figure carries high confidence in CookScale's 120-ingredient table. 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 Baking Powder on a kitchen scale instead of trusting the cup. Read more about this ingredient on the Baking Powder hub, which covers its weight, its measures, its storage and its substitutes in one place.

Practical guidance

Leavening loses strength with age and damp, so a pound of it is only a bargain if you bake often enough to use it while it is fresh. Airtight container, cool and dry, up to 6 months once opened. Test old baking powder with hot water; if it does not fizz immediately, buy a fresh tin. Date the tin when you open it, and test it before an important bake — a failed rise wastes the whole batch, not just the leavening.

Buying and storing a pound of Baking Powder

A pound of leavening is a professional quantity for a home cook, but it is cheap, so the cost of the pound is rarely the issue — the issue is using it before it loses strength. If you bake weekly, a pound lasts a year; if you bake monthly, buy the small tin instead.

How the maths works

The conversion is a single division: one pound is 453.59 g, and one cup of Baking Powder weighs 192 g, so 453.59 ÷ 192 = 2.36 cups. Going the other way, one cup of Baking Powder weighs 192 g, which is 0.42 lb, and one tablespoon weighs about 12.0 g while one teaspoon weighs about 4.00 g. To get any number of cups, weigh that many times 192 g: two cups is 384 g, three cups is 576 g, and half a cup is 96 g. In volume terms, a pound of Baking Powder is about 559 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 Baking Powder; the same pound of a different ingredient would be a different number of cups entirely.

Frequently asked questions

How many teaspoons are in a pound of Baking Powder?

About 113 teaspoons. A pound of Baking Powder is about 2.36 cups, and there are 48 teaspoons in a cup, so 2.36 × 48 is about 113. A single teaspoon weighs about 4.00 g.

Can I use too much Baking Powder?

Yes, and it is the most common leavening mistake. Too much Baking Powder leaves a bitter, metallic or soapy taste and can make a cake rise fast and then collapse in the middle. Measure it level with a knife, never heaped, and never add extra 'for luck'.

How do I know if my Baking Powder is still active?

Stir half a teaspoon into a cup of hot water. It should fizz immediately and vigorously; if it does not, buy a fresh tin.

How should I store a pound of Baking Powder?

In an airtight container in a cool, dry place. Airtight container, cool and dry, up to 6 months once opened. Date the tin when you open it, and test it before an important bake — a failed rise wastes the whole batch.

Can I use baking powder instead of baking soda?

Not one-for-one — baking powder is weaker, so you need about three times as much, and it brings its own acid while baking soda needs acid in the recipe. A teaspoon of baking soda needs roughly a tablespoon of baking powder to lift the same batter.
