To convert grams of instant yeast into tablespoons, multiply by 0.11111111: one gram comes to 0.11111111 tablespoons. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Put next to water — 1 g per mL exactly — instant yeast measures 0.60865 g per mL. That ratio, 60.87%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A level tablespoon of instant yeast is 9 g, which puts a teaspoon at 3 g and a tablespoon and a half — the quantity recipes are fondest of — at 13.5 g. Levelling twice is where the error comes from, so the scale is the faster instrument once the quantity passes a couple of spoons.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.694% of a cup of instant yeast, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 3.472 cups, and a 1 kg pack 6.944.
The condition this weight assumes: Three grams to a teaspoon, so a standard 7 g sachet is a little over two and a quarter teaspoons.
The formula
grams- The amount of instant yeast you are converting, in grams
0.111111111111- Tablespoons per gram for instant yeast, from its density of 0.60865 g/mL
tablespoons- The equivalent quantity in tablespoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.111111111111, the tablespoons-per-gram figure for instant yeast.
- The result appears in tablespoons, with a second reading in tsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of instant yeast in tablespoons
50 g of instant yeast weighs out at 5.55556 tablespoons. Divide 5.55556 by 0.11111111 and you get back to 50 g, which is the quickest check that the factor is the right way up.
150 g of instant yeast in tablespoons
Take 150 g of instant yeast: 150 × 0.11111111 gives 16.6667 tablespoons. Doubling the batch takes it to 33.3333 tablespoons, because the relationship is a straight proportion once the density is known.
500 g of instant yeast in tablespoons
A recipe calling for 500 g of instant yeast needs 55.5556 tablespoons on the scale. The arithmetic is 500 × 0.11111111 = 55.555556, and halving the recipe halves the weight to 27.7778 tablespoons.

Frequently asked questions
How many tablespoons are in 1 g of instant yeast?
One gram of instant yeast is 0.11111111 tablespoons. Half that quantity is 0.0555556 tablespoons and double it is 0.222222 tablespoons, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of instant yeast not 236 g like water?
Because weight per cup depends on what is in the cup. Instant yeast has a density of 0.60865 g per mL where water has 1.00, so a cup of it weighs 144 g rather than 236.6 g. That is a difference of 92.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of instant yeast by roughly 20% — about 14.4 g either side of 144 g — because three grams to a teaspoon, so a standard 7 g sachet is a little over two and a quarter teaspoons. Weighing removes the question entirely.
Is a fluid ounce of instant yeast the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of instant yeast weighs 0.6349 oz, so the two readings differ by 36.5%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of instant yeast would weigh 152.16 g instead of 144 g — 8.16 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
A scale, if the result matters. Volume measuring carries a spread of about 20% for instant yeast — roughly 28.8 g on a 144 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How much does 3 tbsp of instant yeast weigh?
3 tbsp of instant yeast comes to 27 g, or 27 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the tablespoons-to-grams page does it in the direction the question is usually asked.
