Baker's Conversion Tool & Kitchen Assistant

Instant conversions for pizza, focaccia, and bread dough: yeast, spoons to grams, liquid density, and US cups.

Why do professional bakers always measure in grams?

Baking is exact culinary chemistry. Professional bakeries and pizzerias operate with baker's percentages, calculating all ingredients strictly as a percentage of total flour weight (100%).

Volumetric measurements (spoons, cups) cause severe deviations: compressed flour can easily weigh 30% more per cup, while liquids like olive oil and honey have vastly different densities than water. Our conversion tool translates any recipe to exact, repeatable grams in seconds.

Yeast & Leavener Conversion

Instantly switch between fresh cake yeast, instant dry yeast (IDY), active dry yeast (ADY), and active sourdough starter.

grams
Standard sizes:
Fresh Cake Yeast 21 g 3:1 ratio to instant yeast
Instant Yeast (IDY) 7 g Mix directly into flour
Active Dry Yeast (ADY) 8.8 g Dissolve in lukewarm water first
Sourdough (100%) 105 g 100% hydration
Dough compensation for flour & water with sourdough:

Because 100% hydration sourdough starter is half flour and half water, deduct these amounts from your main dough recipe: -52.5g flour & -52.5g water in your dough.

Fresh Cake Yeast Instant Yeast (IDY) Active Dry Yeast (ADY) Sourdough (100%)
1 g 0.33 g 0.42 g 5 g
3 g 1 g 1.25 g 15 g
7 g 2.3 g 2.9 g 35 g
21 g 7 g (1 zakje) 8.75 g 105 g
25 g (1/2 blokje) 8.3 g 10.4 g 125 g
42 g (1 blokje) 14 g (2 zakjes) 17.5 g 210 g

* Vuistregel: 1 gram instant droge gist = 3 gram verse gist. Actieve droge gist los je eerst op in handwarm water (35°C).

Frequently Asked Questions on Baker Conversions

How much fresh yeast equals a 7g packet of instant yeast?
A 7-gram packet of instant dry yeast (IDY) equals exactly 21 grams of fresh cake yeast (a 1:3 ratio). Half a fresh yeast block (21g-25g) replaces one packet of dry yeast.
How many grams are in 1 teaspoon of salt or yeast?
1 level teaspoon of fine sea salt weighs approx. 5.5 grams. 1 level teaspoon of instant dry yeast weighs approx. 3.1 grams. Coarse salt weighs approx. 4.2 grams due to air gaps.
Does 100 ml of olive oil weigh 100 grams?
No. Extra virgin olive oil has a density of approximately 0.92 g/ml. 100 ml of olive oil weighs exactly 92 grams.
Why are volumetric cups inaccurate for pizza flour?
Flour compresses easily. Depending on scooping technique, 1 US cup of Tipo 00 flour ranges from 115g to 155g, altering your intended dough hydration by up to 10%.
