3/4 Cup Active Dry Yeast in Grams
3/4 cup of active dry yeast weighs 108 g (spooned and levelled, King Arthur Baking). Dormant yeast granules that must be dissolved in warm water before use. All the figures on this page are approximate conversions based on the King Arthur Baking value of 144 g per cup, so when a recipe really matters, verify with a kitchen scale.
It is used for breads, pizza dough, rolls and brioche. 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.

One tablespoon of active dry yeast weighs about 9 g, and one teaspoon about 3 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 108 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 144 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.
King Arthur lists instant yeast at 144 g per cup; active dry yeast is sold in 7 g packets and has a similar density. We use 144 g with medium confidence.
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 bakery batch of bread
A commercial bread batch calling for 3/4 cup of active dry yeast needs 108 g, though this is far more than any home recipe uses and suggests a very large batch. A home loaf uses a single 7 g packet, so if your recipe genuinely calls for 3/4 cup, check the batch size first: 108 g of yeast in a home loaf would make the dough rise too fast and taste strongly of yeast.
A pizza dough for a party
A pizza dough recipe for a party might use 3/4 cup of active dry yeast at 108 g, though again this is far more than a home batch needs. A home pizza dough uses a teaspoon or two, where the weight is about 3 g per teaspoon. The 108 g figure matters for a commercial batch or a pizzeria, where the yeast is bought in bulk and weighed by the cup.
A brioche for a bakery counter
A brioche recipe for a bakery counter calling for 3/4 cup of active dry yeast needs 108 g, dissolved in warm water before mixing. Active dry yeast must be dissolved first, unlike instant yeast, which can go straight into the flour. Weighing the yeast keeps the bulk batch rising consistently, and checking the expiry date matters because dead yeast will not rise at all.
Why weighing 3/4 cup of active dry yeast 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.
When this conversion matters most
This conversion matters most in commercial baking, where yeast is bought in bulk and weighed by the cup rather than by the packet. A home loaf uses a single 7 g packet, so the 108 g figure for 3/4 cup matters for a bakery batch or a pizzeria. Active dry yeast weighs 144 g per cup, so 3/4 cup is 108 g, though the confidence is medium because the King Arthur figure is for instant yeast and active dry yeast is sold in packets with a similar density. The practical point is that active dry yeast must be dissolved in warm water before use, while instant yeast can go straight into the flour, so check which type your recipe means.
Storage
Cool, dry place; refrigerate after opening and check the expiry date. Dormant yeast granules that must be dissolved in warm water before use. It is used for breads, pizza dough, rolls and brioche. 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.
Common mistakes
The most common mistake is using water that is too hot to dissolve active dry yeast, which kills it; use lukewarm water around body temperature. A second mistake is confusing active dry yeast with instant yeast: they are used in different amounts, with three quarters of a teaspoon of instant yeast equal to one teaspoon of active dry yeast. A third mistake is using yeast past its expiry date, which will not rise at all; check the date and test the yeast in warm water with a pinch of sugar before you commit a whole batch to it.
If you do not have a kitchen scale, the most reliable fallback is the tablespoon: 3/4 cup is 12 level tablespoons, and each one is levelled on its own, so the errors do not stack the way they do in a cup. Spoon dry ingredients in and level them off, and pour liquids in on a flat surface so the spoon is full but not heaped. It takes a minute longer than weighing, but it beats guessing from a cup, and for a dressing or a marinade it is accurate enough. For cakes and pastry, buy a scale when you can: it is the single cheapest upgrade to your baking.
Frequently asked questions
How many grams is 3/4 cup of active dry yeast?
3/4 cup of active dry yeast weighs 108 g, spooned and levelled, using the King Arthur Baking value of 144 g per cup. The confidence is medium, because the figure is for instant yeast and active dry yeast has a similar density. Verify with a kitchen scale when the recipe matters.
How many packets of yeast is 3/4 cup?
About fifteen packets. One packet of active dry yeast weighs 7 g, so 108 g is roughly fifteen packets. That is why a home recipe never calls for 3/4 cup of yeast: it is a commercial batch amount, and a home loaf uses a single packet.
How many tablespoons is 3/4 cup of active dry yeast?
3/4 cup is 12 tablespoons, and one tablespoon of active dry yeast weighs about 9 g. That gives 108 g for the full 12 tablespoons. A teaspoon weighs about 3 g, which is the amount most recipes actually need.
Do I need to dissolve active dry yeast first?
Yes. Active dry yeast must be dissolved in warm water before use, unlike instant yeast, which can go straight into the flour. Use lukewarm water around body temperature: water that is too hot kills the yeast, and cold water will not wake it up.
Can I use instant yeast instead of active dry yeast?
Yes, but adjust the amount: use three quarters of a teaspoon of instant yeast for every teaspoon of active dry yeast. Instant yeast can go straight into the flour without dissolving, and it rises a little faster, so watch the dough rather than the clock.
