3/4 Cup Baking Powder in Grams
3/4 cup of baking powder weighs 144 g (spooned and levelled, King Arthur Baking). Baking soda plus cream of tartar; double-acting, needs only moisture and heat. All the figures on this page are approximate conversions based on the King Arthur Baking value of 192 g per cup, so when a recipe really matters, verify with a kitchen scale.
It is used for leavening cakes, pancakes and quick breads. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Knowing the weight of 3/4 cup, rather than guessing from a measuring cup, keeps the result consistent no matter which recipe you are following, and it lets you scale a recipe up or down without the errors multiplying.
Why weighing 3/4 cup of baking powder beats measuring it in cups
Leavening is the ingredient where accuracy matters most, because the amount decides whether a bake rises, and too much leaves a bitter, soapy taste that cannot be fixed. A home recipe uses a teaspoon, but a commercial batch or a bulk mix uses cups, and then the weight per cup has to be exact. Baking soda and baking powder are dense powders, so a cup measure can be 10 g or more off depending on how it was scooped. Weighing removes that whole source of error, and it is the only reliable way to scale a leavening recipe up without the bake collapsing.

One tablespoon of baking powder weighs about 12 g, and one teaspoon about 4 g. Three quarters of a cup is 12 tablespoons, and it occupies about 177 ml by volume, the same as 3/4 cup of anything, because volume does not change from one ingredient to the next. Only the weight changes, and that is why the table above is organised by weight rather than volume. The table is rounded to the nearest tenth of a gram where the fraction demands it, so the numbers are approximate by design; the 3/4 cup figure of 144 g is the one to use when a recipe calls for 3/4 cup.
How the weight was measured
Spooned and levelled is the method used for this ingredient, and it matters because the same cup can hold a different weight depending on how it was filled. Spooned and levelled means spooning the ingredient into the cup and levelling the top with a straight knife, without packing it down. Packed means pressing the ingredient firmly into the cup until it holds its shape. Poured means pouring a liquid into a measuring jug up to the line. Scooped means pushing the cup through a solid fat and levelling the top.
The source for the 192 g per cup figure is King Arthur Baking, and this page follows that value exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
All the figures on this page are approximate conversions. When a recipe really matters, verify with a kitchen scale: weigh the ingredient directly into the bowl on a tared scale and trust that number over any cup.
Worked examples
A commercial batch of pancakes
A commercial pancake batch calling for 3/4 cup of baking powder needs 144 g, though this is far more than any home recipe uses and suggests a very large batch. A home pancake recipe uses a tablespoon or two, where the weight is about 12 g per tablespoon. If your recipe genuinely calls for 3/4 cup, check the batch size first: 144 g of baking powder in a home batch would make the pancakes taste bitter and metallic.
A bulk scone mix for a bakery
A bakery scone mix calling for 3/4 cup of baking powder needs 144 g, blended with the flour so every scone rises the same way. Baking powder is the leavening in scones, and the amount has to be right: too much makes them bitter and coarse, too little leaves them flat. Weighing 144 g and mixing it evenly through the flour keeps a bulk batch consistent from the first scone to the last.
A cake recipe, scaled up for a wedding
Scaling a cake recipe up for a wedding might call for 3/4 cup of baking powder at 144 g, mixed into a large amount of flour. The leavening ratio has to stay constant when you scale up, or the cake will rise unevenly and collapse. Weighing the baking powder keeps the ratio exact, and sifting it with the flour distributes it evenly through the batter.
When this conversion matters most
This conversion matters most in baking, where baking powder is the leavening agent and the amount has to be exact. Baking powder is double-acting: it releases gas when it meets moisture and again when it meets heat, so the cake rises twice. Baking powder weighs 192 g per cup, so 3/4 cup is 144 g. In practice, a home recipe uses a teaspoon or a tablespoon, where the weight is about 4 g per teaspoon, and the 144 g figure matters for a commercial batch or a bulk mix. The critical point is never to confuse baking powder with baking soda, which weighs 288 g per cup and needs an acid to work.
Common mistakes
The most common mistake is confusing baking powder with baking soda. Baking powder weighs 192 g per cup, while baking soda weighs 288 g, so 3/4 cup of baking soda is 216 g against 144 g for baking powder, and the two are not interchangeable. A second mistake is using too much baking powder, which makes the bake taste bitter and metallic and can cause it to rise too fast and collapse. A third mistake is using baking powder that has been open for more than six months, when it loses its strength; test it by dropping a little in hot water and watching for fizz.
If you do not have a kitchen scale, use the tablespoon as your measure: 3/4 cup is 12 level tablespoons, and counting them out is more accurate than filling a cup, because each spoonful is levelled individually. For dry ingredients, spoon the ingredient into the tablespoon and level it with a straight knife; for liquids, fill the spoon to the brim on a flat surface. It is slower than weighing, but it is far more reliable than a cup, and it will get you close enough for most recipes. For baking, though, a scale is worth buying: even a cheap one pays for itself the first time a cake comes out right.
Storage
Airtight container, cool and dry, up to 6 months once opened. Baking soda plus cream of tartar; double-acting, needs only moisture and heat. It is used for leavening cakes, pancakes and quick breads. Knowing how the ingredient is stored matters for the conversion too: an ingredient that has absorbed moisture or dried out will weigh differently per cup, so store it properly and weigh it fresh for the best results.
Frequently asked questions
How many grams is 3/4 cup of baking powder?
3/4 cup of baking powder weighs 144 g, spooned and levelled, using the King Arthur Baking value of 192 g per cup. The figure is approximate, so verify with a kitchen scale when the recipe matters. Most home recipes use far less than this, so check the recipe if it calls for 3/4 cup.
How many tablespoons is 3/4 cup of baking powder?
3/4 cup is 12 tablespoons, and one tablespoon of baking powder weighs 12 g. That gives 144 g for the full 12 tablespoons. A teaspoon weighs about 4 g, which is the amount most recipes actually need.
Is baking powder the same as baking soda?
No. Baking powder contains baking soda plus cream of tartar, so it needs only moisture and heat to work, while baking soda needs an acid. They weigh differently too: 3/4 cup of baking powder is 144 g against 216 g for baking soda, so never swap them by weight.
How do I test if baking powder is still active?
Drop a little baking powder into hot water: if it fizzes vigorously, it is still active. If it barely bubbles, it has lost its strength and should be replaced. Baking powder keeps for up to six months once opened, so test it before a big bake.
What happens if I use too much baking powder?
Too much baking powder makes the bake taste bitter and metallic, and it can rise too fast and then collapse in the oven. Weigh the baking powder carefully, and use only the amount the recipe specifies.
