Leavening Grams to Cups Converter
Convert baking soda, baking powder, active dry yeast, instant yeast, and fine salt between grams, teaspoons, and cups.
Direct Answer
Not all leavening agents weigh the same. A cup of baking soda is 220g, double-acting baking powder is 192g, and active dry yeast is 150g. Pick your exact agent below.
Because different ingredients within the leavening category have varying particle sizes and moisture levels, measuring by weight in grams ensures perfect baking results.

Density Dynamics in Leavening
Micro-ingredients like chemical leaveners and bio-yeasts require rigorous weight control. Pure sodium bicarbonate (baking soda) is a dense crystalline powder weighing 220 grams per cup (4.6g per tsp). Commercial baking powder combines baking soda with monocalcium phosphate, sodium aluminum sulfate, and cornstarch buffer; this blend reduces bulk density to 192 grams per cup (4.0g per tsp). Granular active dry yeast and instant yeast consist of dehydrated yeast spheres weighing 150 grams per cup (3.1g per tsp). Over-measuring leaveners by even 2 grams causes bitter chemical flavors and collapsed cake structures.
Leavening Substitution Rules: Weight vs Volume
Never swap baking soda and baking powder 1:1 by weight or volume. Baking soda is 3x to 4x stronger in leavening power than baking powder and requires an acid reactant (buttermilk, lemon juice). To replace 1 tsp baking soda (4.6g), use 3 tsp baking powder (12g) and remove acidic ingredients.

Frequently Asked Questions: Leavening Conversions
How many grams is 1 teaspoon of baking soda?
One level US teaspoon of baking soda weighs 4.6 grams (220g per cup).
How many grams is 1 teaspoon of baking powder?
One level US teaspoon of baking powder weighs 4.0 grams (192g per cup).
How many grams are in a standard packet of active dry yeast?
A standard US packet of yeast contains 7 grams (¼ ounce or approx 2¼ teaspoons).
Can I swap instant yeast for active dry yeast 1:1 by weight?
Yes, instant yeast and active dry yeast have identical weight metrics (150g/cup, 3.1g/tsp) and swap 1:1 by weight in grams.
Why does baking powder weigh less per cup than baking soda?
Baking powder includes light cornstarch filler to separate the acid and base salts, lowering its density from 220g/cup down to 192g/cup.
