Instant Yeast Measurement Converter

Use the tool below to convert instant yeast from the measurements in your recipe to the measurements that you need.

Instant yeast is a finely milled dry yeast that mixes straight into dry ingredients without proofing first. One metric cup (250 ml) of instant yeast weighs around 150 grams or 5.29 ounces, though recipes almost always measure it by the teaspoon or sachet (a 7 g sachet equals about 2 1/3 teaspoons). It is the quickest route to a reliable rise in bread, pizza dough, and cinnamon rolls.

Yeast amounts are tiny but matter a lot: too little gives a dense loaf, too much an over-proofed one with a yeasty taste. Weighing in grams is far more accurate than scooping a teaspoon, especially when scaling a recipe up or down.

Also known as

  • fast-acting yeast
  • rapid rise yeast
  • bread machine yeast
  • quick yeast

Related Instant Yeast Ingredients

Active dry yeast is granular and needs proofing in warm liquid before use, unlike instant yeast which goes straight into the dry mix. They are interchangeable 1:1 by weight, so the swap is about method rather than amount. See our Active Dry Yeast converter.

Frequently Asked Questions

Are instant yeast and fast-acting yeast the same thing?
Yes. Fast-acting yeast is another name for instant yeast, so they are the same ingredient and measure identically. A teaspoon of instant yeast weighs 3 grams under either name, and every conversion on this page holds whichever name your recipe uses. Recipes swap the two freely, so you can follow either without changing quantities or weighing any differently.
What is 100g of instant yeast in ounces?
100 grams of instant yeast is 3.53 ounces. This is the same for any ingredient, since grams and ounces are both weight units and do not change with what you are weighing. 200 grams is 7.05 ounces and 50 grams is 1.76 ounces. Use the weight converter to switch between grams, ounces, pounds, and kilograms for any amount. Open the weight converter
How much does a teaspoon of instant yeast weigh?
1 teaspoon of instant yeast in grams is 3 grams. The ratio is fixed, so 2 teaspoons is 6 grams and half a teaspoon is 1.5 grams. Ingredients like instant yeast are usually measured by the spoon, so this is the amount most recipes call for. See the full teaspoon to grams chart for instant yeast for more.
