This automatic yeast equivalents calculator, for yeast alternatives, assumes the (world's standard practice) weight and volume measures are: Active dry yeast = 0.25 ounce per 2-1/2 teaspoons, Instant yeast = 1 ounce per 3 tablespoons. Fresh compressed baker's yeast weighs 122 - 130 g US measuring cup = 128 - 136 g Metric cup/250mL (for crumbled yeast) and 254 grams per US cup = 268 grams per Metric cup exactly when yeast is tightly pressed into cup (100 percent of all air removed.) Easy convert between these three yeast types - and replace each one yeast for another yeast's replacement/equivalent measure in cups - teaspoons tsp - tablespoons tbsp. I will add also wild yeast right after I learn how to work with it.
You may enter whole numbers, decimals or fractions ie: 7, 29.35, 15 3/4

Yeasts replacing formula calculating method

The yeast calculating math-formula:

1 part instant yeast (100%) = 3 parts fresh compressed yeast (300%) = 1.5 parts active dry yeast (150%)

To convert between various yeast type amounts and to replace one with another is relatively simple, but, the final measuring then should preferably be accurate for achieving a correctly working dough.

Example on how/when to use instant yeast to active dry yeast converter:
Q. 1.5 tablespoons instant yeast converted to active dry yeast
A. 2.25 or 2-1/4 tbsp - tablespoons of ACTIVE DRY yeast replace 1.5 tbsp - tablespoon of INSTANT yeast.
Math : 1.5 tbsp - tablespoon of INSTANT yeast = 2.25 - 2-1/4 tbsp - tablespoons of ACTIVE DRY yeast
Conversion Formula : 1 part of INSTANT yeast = 1-1/2 or 1.5 or one and half parts of ACTIVE DRY yeast

Example for how/when to use fresh yeast to dry active yeast converter:
Q. What is a conversion of 150g fresh yeast to dry active yeast by teaspoons?
A. There are 26-1/2 tsp of dry yeast needed to replace 150 grams of fresh yeast.
Math : 150 g - ( grams ) of FRESH yeast = 26.46 tsp - ( teaspoons ) of ACTIVE DRY yeast
Conversion Formula : 1 part of FRESH yeast = 1/2 or 0.5 or half part of ACTIVE DRY yeast

Replacing yeast with Brewers' yeast

Brewer's yeast math-formula:

1 part of brewer's yeast (100%) = 0.45 part ( ~ 1/2 ) of active dry yeast (45%)
1 part of active dry yeast (100%) = 2.2 parts of brewer's yeast (220%)

Brewer's yeast, even though it is nutritionally rich in protein, chromium, selenium and B vitamins it does not contain essential Vitamin B12 so vegetarians take that into account. A great vitamin B12 supplement solution is to take Folate tablets - Folic Acid, B12 and B6 combination (Folate repairs our DNA as well - I have one table every day.) OK back to the brewers yeast, it is slow-rising yeast (because it produces ethanol instead of carbon dioxide which faster yeasts make), dough will rise much longer even if more yeast was added. Which means; dough can rise more than once, therefore, it can be used to add more flavor or texture into certain/quite marvelous baking. We use it with harder coarser flours, the Spelt flour is just one example.

Measuring weight of 1 cup volume of Brewer's yeast :

Cup of powdered Brewer's yeast.
Brewer's yeast powder
measuring the mass of 1 cup

Sachet of instant yeast ...

One sachet of instant yeast from a box may weigh anywhere between 5g to 15g therefore notice this weight number on the original yeast packaging.

I prefer to use the instant yeast as it contains a lot more of yeast living cells, 4 times more than active dry yeast and by 300% more than the compressed fresh yeast. And I also bake a lot with adding the brewers yeast as it produces much nicer flavours and it is healthier to digest - use the calculator above to work our the optimal equivalent amounts to replace other yeasts for powdered brewers' yeast type.
